Assignment:
Q1. A crate is supported by three cables as shown. Determine the weight of the crate knowing that the tension in cable AB is 750 lb.
Q2. A rectangular plate is supported by three cables as shown. Knowing that the tension in cable AC is 60 N, determine the weight of the plate. (480 is cut off)
Q3. The direction of the 75- lb forces may vary, but the angle between the forces is always 50°. Determine the value of a for which the resultant of the forces acting at A is directed horizontally to the left.
Provide complete and step by step solution for the question and show calculations and use formulas.
