Question

The tension in the cord is equal to:
A. The weight B. The forces Q + S C. The forces S + P The force of the blow is so great that the player's femur is broken. The player is required to spend some time in traction. The Russell system of traction, which was used, is diagramed in Figure 3. Figure 3 The forces S, Q, and P are all equal in magnitude and equal in magnitude to the tension in the cord. The vector sum or resultant of the forces S, Q, and P is the force pulling on the femur. With respect to the horizontal, S makes an angle of 20° below, Q an angle of 30° above, and P an angle of 45° above.

Explanation / Answer

From the diagram
it is given that tension in P, Q , R and S is equal and equal to the tension in the cord

now the cord is connectged to the weight and the weight is not moving
hjence the tension in the chord is equal to the weight of the block

so tension in the cord is equal to the weight of the block
