Sample Problem 12

A Load W is supported by three cables as shown. Determine the value of W, knowing that the tension BD is 390 lb.

Sample Problem 11

Express the weight W required to maintain equilibrium in terms of P, d, & h.

Sample Problem 10

A 300 lb force is applied at point C for what values of θ is the tension in cable AC minimum? What are the corresponding values of the tension in cables AC and BC?

Here's the Solution:
