In a simply-supported beam loaded as shown below, the maximum bending moment in N-m is

A beam is made up of two identical bars AB and BC, by hinging them together at B. The end A is built-in (cantilevered) and the end C is simply supported. With the load P acting as shown, the bending moment at A is

A mass of 35 kg is suspended from a weightless bar AC, which is supported by a cable CB and a pin at A as shown in Fig. below. The pin reactions at A on the bar AB are

Two bars AB and BC are connected by a frictionless hinge at B. The assembly is supported and loaded as shown in Fig. Draw the shear force and bending moment diagrams for the combined beam AC, clearly labeling the important values. Also indicate your sign convention.
