    Friction Shaft
AI Thread Summary
The discussion revolves around a physics problem involving two collars sliding on vertical rods, connected by a cord over a fixed shaft. The static friction coefficient is given as 0.2, and the weight of collar B is specified as 10 lb, while collar A's weight is neglected. Participants are required to determine the range of force F needed to maintain equilibrium in this system. The forum emphasizes the importance of showing attempts at solving the problem before receiving assistance. Overall, the focus is on applying static friction principles to analyze the forces at play in the scenario.

Homework Statement


Two collars A and B can slide on vertical rods. Collar A and collar B are connected by a cord that passes over a fixed shaft at C. the static friction coefficient of any two contact surfaces is 0.2. the weight of collar B is 10 lb, neglect collar A's weight, determine the range of force F required to maintain the equilibrium.

Thread 'Have I solved this structural engineering equation correctly?'

Hi all, I have a structural engineering book from 1979. I am trying to follow it as best as I can. I have come to a formula that calculates the rotations in radians at the rigid joint that requires an iterative procedure. This equation comes in the form of: $$ x_i = \frac {Q_ih_i + Q_{i+1}h_{i+1}}{4K} + \frac {C}{K}x_{i-1} + \frac {C}{K}x_{i+1} $$ Where: ## Q ## is the horizontal storey shear ## h ## is the storey height ## K = (6G_i + C_i + C_{i+1}) ## ## G = \frac {I_g}{h} ## ## C...
