Question $1$:

Determine the internal normal force, shear force, and bending moment in the beam at points C

and $D.$ Assume the support at $A$ is a pin and $B$ is a roller.

Question $2$:

Determine the internal normal force, shear force, and bending moment in the beam at points C

and $D.$ Assume the support at $A$ is a roller and $B$ is a pin.

Question $3$:

The boom DF of the jib crane and the column DE have a uniform weight of $50l\frac{b}{f}t.$ If the hoist

and load weigh $300$ lb $,$ determine the internal normal force, shear force, and bending moment

in the crane at points $A,B,$ and C $.$
