In Condition A, when the cargo is stationary, there is no acceleration. Therefore, the net force on the cargo is zero.
The weight of the cargo, W, is acting downward, and the tension, FT, in the steel cable is acting upward. To have a net force of zero, the tension must be equal in magnitude to the weight. Therefore, the tension in Condition A is equal to the weight of the cargo.
Tension in Condition A = Weight (W)
Given DIAGRAM 1.1 where FT means Tension and W means Weight, calculate the tension on the steel cable given the following conditions:
A. The cargo is stationary.
B. The cargo accelerates upward at a rate of 0.25 m/(s^2)
What is the tension in Condition A?
