Question description

a stick with a length of 1 meter is supported by a knife edge at the 50 cm make (in the middle). 2 masses m1=.40kg and m2=.60kg are hanging, 1 (m1) at 10 cm from the left end of the stick and the other one  (m2) at 35 cm from the right end of the stick. Take 9=10m/s^2

a. calculate the torque created by hanging the mass m1

b. does the torque rotate the stick clockwise or counterclockwise

c. calculate the torque created by the hanging mass m2

d. does this torque rotate the stick clockwise or counter clockwise

e. where should you place a 3rd mass m3 such that the stick is in equilibrium?

1. closer to m1

2. closer to m2

3. it does not matter

f. find the distance from the support where the 3rd mass m3=.3kg should be placed for the stick to be in equilibrium
