Answer:
3947.6 N
Explanation:
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 = mω²r ........................ Equation 1
Where F = Centripetal force, ω = angular velocity, r = radius.
Where π = 3.1415
Given: m = 4 kg, ω = 0.5 rev/s = (0.5×2π) 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
