Please solve the problem with a neat paper sheet. The length AB for the lug wrench shown below is 12 inches. What is the maximum force (F) that one can apply on the handles without yielding the material (Steel: Sy = 45 ksi). The diameter of the wrench is 0.625 inch.
Look at the following arrangement. Block A is held at rest on the frictionless wedge B by a massless rope that passes over a massless and frictionless pulley attached to the ceiling. The wedge sits on a scale. The wedge is not anchored in any way to the scale, and it is initially held at rest by a hand in such a way that the rope on the left of the pulley is oriented vertically. a) What is the scale reading after letting go of the wedge gently until the wedge comes to rest? b) What is the orientation of the rope after letting go of the wedge gently until the wedge comes to rest?
