Question

Spring scale A is attached to the floor and a rope runs vertically upward, loops over the pulley, and runs down on the other side to a 120-N weight. Scale B is attached to the ceiling and the pully is hung below it. What are the readings if the two spring scales A and B?

Explanation / Answer

Scale A reading = tension in rope =T = 120 N

.

Scale B reading = tension in rope carrying pulley = 2 * T

= 2* 120 = 240 N
