The mobile in the figure below is in equilibrium.
The object B has mass of 0.605 kg. Determine the mass of object C. Assume L1 = 28.0 cm, L2 = 7.60 cm, L3 = 13.6 cm, L4 = 5.90 cm, L5 = 16.1 cm and L6 = 5.90 cm. (Neglect the weights of the crossbars.)© BrainMass Inc. brainmass.com March 4, 2021, 5:40 pm ad1c9bdddf
Two equilibrium laws apply to each crossbar:
<br>(1) total upward force must equal total downward force, and
<br>(2) about any axis, total clockwise torque = total counter clockwise torque.
<br>Note: Force of gravity on any mass is: M g
<br>Applying (2) to the ...
