How long does it take a skateboarder to roll from the top of a half pipe of radius 2 meters to the bottom? Ignore friction, and assume the half pipe is in the shape of a semi circle. I tried to use integration to solve this but failed miserably, would someone please show me how to do this? Show...
Homework Statement
Hey, need a quick bit of help, Maths Physics end of year exam and I can't find how to calculate the moment of inertia of a non uniform bod thin rod.
I'll post the question here for reference -
1. A rod AB of length 3m has non-uniform density x 15 − 2xkg/m...
How to deal with non uniform cross section bending?
How does one approach a solution for bending of a shaft having multiple diameters.
I have one particular shaft in mind that has 11 diameters to get to the midpoint.
I know the deflection at the midpoint, and I would like to calculate...
1st I am having problems getting a solution for final Velocity in terms of Distance traveled with a non-zero initial velocity.
Acceleration = A / Velocity - B * Velocity^2
where A is a constant related to Hp (horsepower) of the vehicle and and B is a constant related to aerodynamic...
Hi. *Problem solved.
A trolley of mass 930 g is held on a horizontal surface by means of two springs,one spring on the left and right respectively.The variation with time t of the speed v of the trolley for the first 0.60s of its motion is shown in the fig(It's a v-t graph,max y=8.0cms^-1...
I Would like to come up with the capacitance between an infinite sheet and a finite area rectangle as a function of distance. I looked into my old E&M book, it did not consider edge effects I need to include those.
Here is the situation. I just spent the day working with a capacitive sensor...
A car is at rest in a circle of radius r. The car then accelerates, but friction limits the speed to some max speed v. At what angle is the max speed v reached? (calculus is involved).
The key is to draw a detailed FBD, which I need help with. So far the forces I have are: centripital...
What are the Forces of a car that is accelerating around a circle? There is friction between the road and the car.
Centripital force(in towards the circle)
Static Friction(in towards the circle)
However there is also another component of friction that I am missing?
Any ideas?
Thanks
Hi:
I have a very big concern about my mechanics homework because a problem says: "Find a formula that gives the position of the center of gravity and make sure that in the limiting case of a uniform gravitational field your formula predicts that both center of gravity and center of mass...
A computer disk is 8.0cm in diameter. a refrence dot on the edge of the disk is initially located at theta= 45 degrees.
The disk accelerates steadily for 1/2 second, reaching 2000 rpm, then coasts at steady angular velocity for 1/2 second.
what is the speed of the refrence dot at 1...
This is really frusterating me, my book provides horrible examples and i have no idea how to go about this problem.
There is a cube with sides L= .3m and an electric field = (-5 N/C X m) x i +(3 N/C x m) z k i= i hat k= k hat
I know that the flux = the integral of the E ...
non uniform circular motion?
A .400 kg object is swung in a vertical circular path on a string 0.500m long. If it's speed is 4.00 m/s at the top of the circle, what is the tension in the string there?
i drew my free body diagram and have tension pointing up in the positive y direction. the...
