Determine the tension in each of the three ropes supporting the 800-lb crate.

Chapter 5, Problem 5.33P, Determine the tension in each of the three ropes supporting the 800-lb crate.

To determine

Tension in each rope.

Explanation of Solution

Given Information:

800-lb crate is supported by three ropes as shown in following figure:

Calculation:

Draw free body diagram of as shown in following figure:

Force vectors are,

  TB=TB( 6 i ^ 6 j ^ 10.5 k ^ 6 2 + (6) 2 + (10.5) 2 )=TB(0.46i^0.46j^0.81k^)TC=TC( 6 i ^ 3 j ^ 10.5 k ^ (6) 2 + (3) 2 + (10.5) 2 )=TC(0.5i^0.25j^0.87k^)TD=TD( 2.4 i ^ +6 j ^ 10.5 k ^ 2.4 2 + (6) 2 + (10.5) 2 )=TD(0.2i^0.5j^0.87k^)W=800k^

Take equilibrium of forces as,

  F=0TB+TC+TD+W=0TB(0
