Question

calculate the centripetal force on the end of
100 m( radius) wind turbine blade that is
rotating at
0.5 rev/s. Assume the mass is 4kg.​

Answer 1

Answer:

Centripetal Force: This is the force that tend to moves a body towards the center of a circle during circular motion.

The formula for centripetal force is

F = mw²r

Equation 1

Where F = Centripetal force, w = angular

velocity, r = radius. Where = 3.1415

Given: m = 4 kg, w = 0.5 rev/s = (0.5×2m) rad/s = 3.1415 rad/s, r = 100 m.

Substitute into equation 1

F = 4(3.1415)²(100)

F = 3947.6 N

Hence the centripetal force on the turbine blade = 3947.6 N
