Question

The drawing shows three identical springs hanging from the ceiling. Nothing is attached to the first spring, whereas a W = 5.03-N block hangs from the second spring. A block of unknown weight hangs from the third spring. From the drawing, determine the spring constant (in N/m) and the weight of the block hanging from the third spring.

(a) the spring constant?

(b) the weight of the block hanging from the third spring?

Explanation / Answer

Fg = K*dy

k = W/y = 5.03/(0.35-0.2) = 33.53 N/m

b) W = k*dy1 = 33.53*(0.5-0.2) = 10.059 N
