Determine the tension developed in each cord required for equilibrium of the 20-kg lamp. (Figure 1)
A) Determine the tension developed in cord DF.
A cylinder having a mass of 250 kg is to be supported by the cord that wraps over the pipe. Determine the largest vertical force F that can be applied to the cord without moving the cylinder. The cord passes
(a) once over the pipe, β=180, and
(b) two times over the pipe, β=540.
Take μs=0.2.
