Question

(a) Assume that the string is vertical (it is perpendicular to the bar). Use the equilibrium equation for the torques to find m2. (Your answer should be in terms of m1, d1, and d2.)
m2 =

(b) Now consider the actual setup with the string at an angle to the vertical. Again use the equilibrium equation for the torques to find m2. (Your answer should be in terms of m1, d1, d2, and .)
m2 =

(c) How much additional mass does the student have to add to the bucket to correct this error? (Your answer should be in terms of m1, d1, d2, and .)
m =

Explanation / Answer

part A.
m1*g*d1 - m2*g*d2 = 0
m1*d1 - m2*d2 = 0
m1*d1 = m2*d2
(m1*d1)/d2 = m2'

part B
same thing just d2* cos(?) so,

(m1*d1)/(d2 * cos(?)) = m2

for part C.

answer A - answer B
(m1d1) / d2 - (m1d1) / (d2cos(?))
