Explanation / Answer

Given that,

mb = 81.6 kg

mc = 22.3 kg

(a)

Maximum tension in chain,

Tmax = (mb + mc)*g

Tmax = (81.6 + 22.3) * 9.8

Tmax = 1018.22 N

(b)

minimum tension in the chain,

Tmin = mb*g = 81.6*9.8

Tmin = 799.68 N

(c)

Tension at a point 3/4 from the bottom of the chain,

T = [(3/4)*mc + mb] * g

T = [(3/4)*22.3 + 81.6] * 9.8

T = 963.58 N
