The bar ABC is supported by three identical, ideal springs. Note that the springs are always vertical because the collars to which they are attached are free to slide on the horizontal rail. Find the angle at equilibrium if W = kL. Neglect the weight of the bar.
The coeffient of static friction between the uniform bar AB of weight W and the ground is 0.45. Find the smallest angle and the corresponding force P that would initiate simultaneous tipping and sliding of the bar.
The linkage is made of two homogenous bars of weights shown in the figure. Determine the horizontal force P required to hold the linkage in the position shown.

A system is being designed to lift objects with a cable. One end of the cable will be attached to the material while the other end will be permanently fixed to a drum (cylinder) so that as the drum is rotated the cable is wound around its outside surface. Two designs for a drum are being considered for use in the system. Design “A” calls for a solid aluminum pulley (paluminium = 2800 kg/m 3 ) while design “B” calls for a steel pulley (psteel = 8000 kg/m 3 ) that is hollow (it can be modeled as a 12 mm thick shell). Calculate the torque required to accelerate the pulley for Design B to reach 500 RPM in 4 seconds if the pulley is 500 mm wide. Assume constant
Given the truss below, solve the force experienced by each members and indicate if it is a compression or tension force. Box your final answers. Follow the step by step guide from the previous lesson.
The boxes each have mass m, and are held stationary by the systems of ropes and ideal (massless,frictionless) pulleys as shown. Shaded regions are fixed supports.Find the tensions in the labeled ropes.Express your answers in terms of mg. Show your work.You do not need to use the full recipe, but do draw free-body-diagrams!Please summarize your results in a table to make marking easier.
A ladder, 8 m long and having a mass of 25 kg, rests on a horizontal floor and is supported by a vertical wall. The ladder is inclined 62°, as shown, and starts to slip when a person having a mass of 73 kg has climbed halfway up it. The coefficient of friction at the wall is 0.20. Assume the weight of the ladder to be concentrated at its midpoint. Calculate the coefficient of friction at the floor. - Draw a free-body diagram - Solve most simple way
