Question

A.)For both parts of the experiment, when the forces are balanced, discuss the agreement between ? ?ccw and ? ?cw. Are the experimental results sufficiently close to consider that the data verifies the theory? Explain your answer.

B.)In part 1 of the laboratory, what is the value of the force Fs with which the support pushes upward on the meter stick? Show your work.

Explanation / Answer

(a)

As the forces are balanced, there will be no translational motion along any direction.

in the first experiment, the clockwise and counterclockwise torques are balances, so, the system will be in rotational equilibrium.

in the second experiment, the counterclockwise torque is greater than that of the clockwise torque.so, the system rotates in counterclockwise direction.

(b)

the net vertical force on the meter stick is zero as it is not moving in this direction.

Fs- (m1+m2)g=0

Fs=(0.1162 +0.2162) (9.8)= 3.25752 N
