A stone

There is a stone weighing 60 kg on the billet. The distance from the support point to the stone is 20cm. The length of the billet is 1m. Determine the force exerted by the hand at the end of the billet.

Correct answer:

F2 =  117.72 N

Step-by-step explanation:

g=9.81 m/s2 m=60 kg F1=m g=60 9.81=29435=588.6 N M1=M2 r1=0.20 m r2=1.00 m F1 r1=F2 r2 F2=F1 r1/r2=588.6 0.2/1=117.72 N
