Answer to Question #70715 in Mechanics | Relativity for Manpreet

Question #70715
A 80kg uniform beam is 10m long and supported horizontally at one end A and at point C which us 3m from the other end B.

What is the maximum load ( in Newtons) that can be placed from B before the beam tips? Hint: the beam will start to tip when the reaction force at point point.

Once you have the maximum load calculate the reaction force at point C.
Expert's answer
Forces in equilibrium:
mg+W=R_A+R_C
R_A=0
Moments in equilibrium:
mg(10/2-3)=W(3)
mg(2)=W(3)
The maximum load:
W=2/3 mg=2/3 80(10)=533 N.
The reaction force at point C:
R_C=mg+W=mg+2/3 mg=5/3 mg=5/3 80(10)=1333 N.
