**Problem 514**

The right-angled frame shown in Fig. P-514 carries a uniformly distributed loading equivalent to 200 N for each horizontal projected meter of the frame; that is, the total load is 1000 N. Compute the maximum flexural stress at section a-a if the cross-section is 50 mm square.

**Problem 452**

For the frame shown in Figure P-452, determine the horizontal and vertical components of the hinge force at B as it acts upon member AC.

**Problem 451**

The frame shown in Figure P-451 is hinged at E and roller supported at A. Determine the horizontal and vertical components of the hinge forces at B, C, and D. Neglect the weights of the members.

**Problem 450**

The billboard BC weighing 1000 lb is subjected to a wind pressure of 300 lb/ft as shown in Figure P-450. Neglecting the weights of the support-members, determine the component of the hinge forces at A and F.
