Question 1:
The ACD frame is fixed using the supports A and D. It is supported by a cable which passes through the ring B and is fixed to the wall by hooks at points G and H. The tension in the cable is 450N.
Determine the moment of force exerted by the section BG of the cable with respect to the point O (magnitude and direction) and with respect to the axis AD (magnitude).
Present the solution using MRP, providing:
1. The strategy
2. The resolution, including any relevant diagrams;
3. The illustration of the results.
Question 2:
Two forces of 90 kN each act on the metal structure, as shown in the figure below. The weight W = 200 kN of this structure is located in G.
Determine:
a) the equivalent FORCE-COUPLE system at point A by providing the magnitude and direction of the force and the torque;
b) the equivalent UNIQUE FORCE system by providing the position of this unique force on the segment AB.
Present the solution using MRP, providing:
1. the definition;
2. the strategy;
3. the resolution, including any relevant diagram;
4. the illustration of the results.
