Q1:- The coplanar force system shown in Figure below is subjected to a couple moment (M) and three forces. Two forces are known in magnitude and direction and shown in the Figure (150 N and 60 N). The third force is passing through the center of the semi-circle (point C). The resultant of all these forces is a single couple (750 N.m) counterclockwise. a) Determine the magnitude and direction of the third force. b) Determine the magnitude of moment (M). c) Replace the couple (M) by two vertical equal forces acting at D and E. d) Replace the force (150 N) by and single force at D and a couple.

A load P is supported by a structure consisting of rigid bar ABC, two identical solid bronze [E = 15,000 ksi] rods, and a solid steel [E = 30,000 ksi] rod, as shown. The bronze rods (1) each have a diameter of 0.500 in. and they are symmetrically positioned relative to the center rod (2) and the applied load P. Steel rod (2) has a diameter of 0.360 in. If all bars are unstressed before the load P is applied, determine the normal force in steel rod (2) after a load of P = 36 kips is applied.
