Static equilibrium Definition and 360 Threads

Was looking for some assistance in setting up the force and torque balance equations for one of those wine bottle holders where the holder is nothing more than a tilted board with a hole in it. I understand that the C.G. of the system needs to be directly above the base of the board but I want...

I've a test soon, and I've been thinking about this, and not quite sure how to approach it. I think I understand the chapter, but I can't seem to get it. A uniform 210lb telephone pole is sticking out over the Grand Canyon (32 feet of it is sticking out) with a massless cat stuck at the end...

static equilibrium problem A 900-N boy sits on top of a ladder of negligible weight that rests on a frictionless floor as in http://m.domaindlx.com/barnsworth/physics.JPG. There is a cross brace halfway up the ladder, and the angle at the apex is 30 degrees. a) What is the force exerted by...

One end of a uniform 4.00-m long rod of weight Fg is supported by a cable. The other end rests against the wall, where it is held by friction. The coefficient of static friction between the wall and the rod is = 0.500. Determine the minimum distance x from point A at which an additional...

A 50 story building is being planned. It is to be 200 m high with a base 56 m by 70 m. Its total mass will be about 1.8 X10^7 kg and its weight therefore about 1.8 108 N. Suppose a 200 km/h wind exerts a force of 1000 N/m2 over the 70 m wide face (Fig. 12-86). Calculate the torque about the...

Hey all... thanks for looking. I've got three questions that I'm having trouble with... I have some crap done on them, but I'm just plain stuck... can someone help me out with all 3? I need to be done these like yesterday so I can get my mark to the university. :cry: I scanned in the...

there is an object suspended on a frictionless inclined plane by a rope parallel to the incline. (the tension in the rope is 5000N). The angle on the incline is 25. I need help to find the weight of the object, I've tried everything! Thanks.

Hi, I was wondering how to analyze the forces in a simple static equilibrium problem I have been contemplating. Suppose you have two pulleys attached to a wall and aligned horizontally with a loop of wire around them, and you hang a weight from the lower strand of wire. I'm stuck trying to...

I've added a picture. The system shown to the right is in equilibrium with the center string exactly horizontal. Mass # 1 = 42 kg. Mass # 2 = 50 kg. È = 31 degrees. =========== A) Tension in left most string? B) Tension in center string? C) Tension in right string? D) What is the...

Here is a problem I have to solve http://myfiles.dyndns.org/pictures/statics9-2.png The load W is 1250lbs. The force exerted by the hydraulic thing GJ is 0 which makes HF a 2 force member. What I am supposed to do is solve for the tension in spring DE I just can't seem to get an...
