Question
If a leg is suspended by a traction setup as shown in Figure 4.30, what is the tension in the rope?
Step-by-Step Solution
Verified Answer
The tension in the rope is equal to the weight of the leg.
1Step 1: Concept of Normal Force
Whatever supports a load, it must supply an upward force equal to the weight of the load. This upward force is called the normal force.
2Step 2: Determine the tension in the rope
Whatever supports a load, it must supply an upward force called normal force, which is equal to the weight of the load.
Here, the leg is supported by a rope. So, the rope must supply an upward force in the form of tension which must be equal to the weight of the leg.
Hence, the tension in the rope is equal to the weight of the leg.
