Question

While on a camping trip, you would like to carry water from the lake to your campsite. You have two non-identical buckets which you attach to a 1.83 m long rod. Since the buckets are not identical, you find that the rod balances about a point 0.0751 m from its midpoint, as shown below. The weight of the rod and empty buckets are negligible compared to the weight of the water. Which bucket holds more water? Fill in the blank: The heavier bucket contains ___% more water than the lighter bucket does.

Explanation / Answer


apply the principle of conservation of torque

T1 L1 = T2 L2

W1 * ( L/2 + 0.0751) = W2 * ( L/2 - 0.0751

Ration of weightts W2/W1 = (1.83/2 + 0.0751)/( 1.832 - 0.0751))

= 1.1799

w2 = w1 + (17.99% )w1

heavier bucket 18 % more water than lighter bucket
