Two steel pipes are used to support a 50KN load, as shown below. The pipes are connected
to the wall (at points A and C) and each other (at point B) with pin joints. The load is applied
at point B.
a. Draw free body diagrams for the two pipes and the pin joint at point B.
b. Find the support forces at the wall at points A and C.

A homogeneous 200 kg bar with a length of 6 meters carries a 3 kN force at one end. This bar is supported at the other end by a pin on the wall and the center with 10 mm diameter cable attached to the same wall 4 meters above the pin. What is the tensile load on the cable.
Figure 1 below shows the bronze and galvani pipes are fastened to rigid supports at ends A and B and to a rigid plate C at their junction. The bronze pipe is twice as long as the galvani pipe. Two equal and symmetrically placed loads P act on the plate at C.
