A uniform 100-lb beam is held in a vertical position by a pin at its lower end and a cable at its upper end. A horizontal force (magnitude P) acts as shown in the figure. If P = 75 Ib, what is the magnitude of x-component of the force at the pin? Select one: 3,0n a. 69 Ib b. 47 Ib 5.0 n c. 75 Ib d. 28 Ib e. 54 Ib

For the beam shown: (a) determine the distance a for which the maximum positive and negative bending moments in the beam are equal; and (b) draw the corresponding shear and bending moment diagrams for the beam.
