Question
A cylindrical fishing reel has a mass of 0.634 kg and a radius of 3.9 cm. A friction clutch in the reel exerts a restraining torque of 1.52 N · m if a fish pulls on the line. The fish- erman gets a bite, and the reel begins to spin with an angular acceleration of 54 rad/s 2 . What force does the fish exert on the line?

Answer:
Explanation:
Given:
Mass, m = 0.634 kg
Radius, r = 3.9 cm
= 0.039 m
Torque, Trest = 1.52 Nm
Angular acceleration, α = 54 rad/s^2
Torque, T = I × α
Where,
I = moment of inertia
Moment of inertia of a solid cylinder, I = 1/2 × m × r^2
Net torque = summation of all the total torque around the reel
Tfish = Trest + Treel
F × r = Trest + I × α
Inputting values,
0.039F = 1.52 + ((1/2 × 0.634 × (0.039)^2)) × 54)
= 1.52 + 0.026
= 1.546
Solving for Force, F,
F = 1.546/0.039
= 39.64 N
= 39.6 N.
