TL;DR Summary: help with assignment: find CV joint torque in 3 different situations Hi, I need help for my assignment. I need to calculate torque of CV joint of truck in 3 cases: a) CV joint torque on take off b) CV joint torque on take off on a slope in reverse c) CV joint torque while...

Does a bug hitting your windshield slow down your truck?

The equation at the bottom is me attempting to solve for the distance. Without knowing the mass of the box and truck my approach to this problem isn't possible?

I'm interested in making a digital compass that I can install on my truck, just for the fun of it. I've looked online and found some simple 8-point designs, which is probably suitable for what I have in mind, but it did raise the question: What would it take to make one capable of resolution on...

If the truck accelerates at 1.47 fps until it reaches its top speed of 8.8 fps, then it takes approximately six seconds to reach the top speed (1.47 x 6 = 8.82). In its first six seconds, the truck covers 30.87 feet (the truck reaches 8.8 after traveling 23.2 feet). To cover the remaining 57.13...

Is it just me or are there some fundamental problems with this exam question ? What is driving me bananas is you have a moving truck (constant velocity). Then the truck "accelerates" but the block in the back of the truck "stays in the same place". Does this mean relative to the ground...

hey i would like to get some help with this question i try to answer it but it was not correct i like to know what i did wrong and how i can fix it:

If ##F## is constant, then mass is inversely proportional to ##dv/dt##. But ##dv## is constant too. So mass is proportional to ##dt##. More massive the body more time it will take to stop covering more distance. So car will cover less distance. Is my logic right ?

Find the problem and the solution below; Find my approach to the problem. Considering the motion of the car; ##v=u+at## ##33.333= 26.6667+30a## ##a=0.2222## Therefore it follows that, ##s##=## ut##+##\frac {1}{2}####at^2## ##s##=##(26.67 ×30 +(0.5×0.222×30^2)## ##s=900##metres The distance...

Hi everyone is able to help solve this question for my assignment in university? I've draw a free body diagram for each component of the question but now i am stuck. [Mentor Note -- Poster has been reminded to show their work when starting a new schoolwork thread]

If 150s is the time in which overtaking has to occur then why are they using this eqn: xp=x0+xs.

The text gives the answer as 92ºC. The answer is arrived at by doing ##Q=Mgh=mc\Delta T##. But it is unclear to me if they are the same. I checked the coefficient of friction and it definitely seems to be considerable. Is the entire PE lost by the truck going to result in increasing the...

I drew a free body diagram for the crate. I have normal force going up, weight down, static friction force to the left and the force of the crate sliding to the right. I'm assuming the truck is moving to the left. I have Fnet=0 because the crate is not moving, so the forces are balanced. I...

My doubt is whether its correct to assume that the exhaust is having the velocity of truck when it comes out of the exhaust pipe. So, I am not sure if Ve = Vt. Should not the exhaust come out in a south direction from exhaust pipe since truck is moving in north direction? If yes, then it cannot...

(Continuing from the summary...) I want to build this safely, so I am putting this out here for expert advice. My choice for the shape for the aluminum cantilever is angle, T, square tubing or round. The foam is 2” thick, so I’d like to keep the supports at 2” in width and height. I need to...

The question was translated from finnish so apologies if everything doesn't make sense:) and please do tell if the equations are wrong.

Hi guys I'm a truck driver. Not sure if I'm posting in the right place so i apologise. Iv'e been on a course today about trucks. The course leader was talking about forces. A trucks force forwards can be 0.8. Is this true?

A truck passes a point A on a straight level road with a constant velocity of 10 m s -1. At the same instant, an automobile starts from rest at point A and travels in the same direction as the truck, with a constant acceleration of 1.6 m s -2. How long a time does the automobile take to pass...

hey guys need to know the way to find the solution to the problem. Consider a truck which is traveled in a speed of 60km per hour. A package weighs 50 kg is placed inside the truck with side supports to arrest the movement in x and y direction. But the top movement (z axis) is not arrested...

I don't know how to start it Is the truck who make the cylinder roll, initially? If yes, how? Since the truck force would pass by the center of the cylinder.

I tried solving this by assuming the acceleration of the truck and block to be the same so the block would stay on the incline. Also, I would assume truck ma = static friction, block ma = mgsintheta... then I solved for a to plug into 1st equation to get 12990 N. Is this correct? I wasn't sure...

If you do the sum of vertical forces and sum of moments, you're always left with an unknown. Vertical Forces: Ray + Rby + Rcy = 59kN + 45kN (1) Sum of Moments about A: (59 x 1.85) - (Rby x 3.7) - (Rcy x 4.8) + (45 x 6.5) = 0...

The truck stops in a shorter distance if the crate slides but why is this the case considering that friction on the crate does positive work on the truck, since it points left for the crate but right for the truck thereby opposing the braking force? I understand why using the equation 1/2mv^2 =...

Posting from over here in Australia, we've been going through some nasty bushfires and on the news I saw a report of a fire truck that had a full tank of water get flipped on its side and resulting in one fire fighter losing his life - apparently a fire tornado flipped the truck. My question...

A diesel engine explodes and literally shoots out of a tractor pulling truck. Apparently this type of thing is fairly common in the sport of tractor pulling, but it's much more common for the engine to simply explode.

A fully electric mining truck has been built that does not burn fuel. It has a 600 kilowatt-hour battery pack, and they need to discharge about 200 KwH of that every night to keep from overcharging it. The secret: It's loaded at the top of the hill, and unloaded at the bottom. The regenerated...

Hi all, Not sure on how to start this question in the first place, but from what I gathered from the data given I managed to derive this from the question: ##\theta = 53.13\deg## Let inside truck be t, final position be f, and ground be g ##D_{ft} = L## ##D_{fg} = xL## Also, for velocity...

The question asks, "A one-way road has an overpass in the form of a semi-ellipse, 15 ft high at the center, and 40 ft wide. Assuming a truck is 12 ft wide, what is the tallest truck that can pass under the overpass?" I don't think this is a super complicated question yet it proves to be too...

As you can see in the pictures below the trucks are attached to the skateboard with four screws nuts and bolts, with a 2~3mm piece of rubber between the truck and the board. I've always wondered if tightening the screws bolts harder, decreases or increases the strength of the 7-layered plywood...
