Assignment:
Problems:
1. The crate has a weight of 550 lb. Determine the force in each supporting cable.
2. The beam has a weight of 700 lb. Determine the shortest cable ABC that can be used to lift it if the maximum force the cable can sustain is 1500 lb.
3. If the 5-kg block is suspended from the pulley B and the sag of the cord is d= 0.15 m, determine the force in cord ABC. Neglect the size of the pulley.
4. The block has a mass of 5 kg and rests on the smooth plane. Determine the unstretched length of the spring.
5. If the mass of cylinder C is 40 kg, determine the mass of cylinder A in order to hold the assembly in the position shown.
6. Determine the tension in cables AB, BC, and CD, necessary to support the 10-kg and 15-kg traffic lights at B and C, respectively. Also, find the angle θ.
