Let the force exerted on each hand be x and on each foot be y.
Balancing the net force along the vertical direction:
2*x + 2*y = 700 [Multiplication by two as there are two hands and feet]
x + y = 350
The torque about the center of gravity of the man should be balanced:
2x*0.410 = 2*y*0.840
That is, x = (0.840/0.410) * y = 2.049y
Substituting the value of x in terms of y in the above equation, we get: 2.049y + y = 350
(b) => y = 114.8 N
(a) Hence x = 350 – 114.8 = 235.2 N

One end of a meter stick is pinned to a table, so the stick can rotate freely in a plane parallel to the tabletop. Two forces, both parallel to the tabletop, are applied to the stick in such a way that the net torque is zero. The first force has a magnitude of 2.00 N and is applied perpendicular to the length of the stick at the free end. The second force has a magnitude of 6.00 N and acts...
