Question

(I) A box weighing 77.0 N rests on a table. A rope tied to the box runs vertically upward over a pulley and a weight is hung from the other end (Fig. 4-45). Determine the force that the table exerts on the box if the weight hanging on the other side of the pulley weighs ($a$) 30.0 N, ($b$) 60.0 N, and ($c$) 90.0 N.

Step 1

0 N: Given: Weight of box (w1) = 77.0 N, Weight hanging on the other side of the pulley (w2) = 30.0 N Using the equation w1 = w2 + N (where N is the normal force), Substitute the values: 77.0 N = 30.0 N + N Solve for N: N = 77.0 N - 30.0 N = 47.0 N Show more…
