The shaft is supported by a journal bearing at A and a thrust bearing at B. Determine the tension in cable CE and the reactions at A and B when a load P = 110 lb and a couple moment M = 40 lb·in is applied. Assume the bearings are properly aligned. For full credit, you must show these steps: Draw a free body diagram. Write sum of forces acting on the body. Take the sum of moments about point B.

The rigid L shaped bar is supported by a pin at O, is attached to a pulley at B and it rests on a wall at point A, as shown in the figure.  The weight of the mass attached to the pulley is equal to m1 = 10 kg. The bar is subjected to the following external loads (directions as shown in the figure): Distributed load with w1 = 700 N/m and w2 = 300 N/m Couple moment at point O equal to MO = 5 N·m Calculate the support reactions. What is the weight required to cause loss of contact at point A?

A box of mass 100 kg rests on an inclined surface is subjected to a load P.  The coefficient of friction between the surface and the box is equal to μs = 0.40. Find the minimum force required to move the box up on the inclined surface. You must include a FBD to receive full points. Hint: Consider two cases to determine the required load for the box to move.

A spring is attached to points A and B as shown in the figure.  The spring constant, k, is given equal to k = 100 N/m and it is stretched by s = 0.1m.  Distance b = 2 m. Consider the force which the spring exerts on point A only and calculate the moment it produces about the coordinate axes x and y.    Calculate the moment produced by the same force about axis OB. You need to show the expression using numerical values; however, you do not need to complete the calculations to find the value of the moment.
