Solve for F
F = T / r
F = 500 / 0.25
F = 2000 N
Answer:
The force is 2000 N

Formula: I_base = (b × h³) / 3
Plug in the values
I_base = (0.3 × 0.5³) / 3
0.5³ = 0.125
I_base = (0.3 × 0.125) / 3
I_base = 0.0375 / 3 = 0.0125 m
Answer:
Moment of inertia about the base = 0.0125 m

Plug in the values
Efficiency = 1.7 / 2
Efficiency = 0.85
Convert to percentage
Efficiency = 0.85 × 100% = 85%
Answer:
The efficiency is 85%

Formula: _max = M × y / I
Plug in the values
_max = (50,000 × 0.2) / 0.0004
_max = 10,000 / 0.0004
_max = 25,000,000 Pa = 25 MPa
Answer:
Maximum bending stress = 25 MPa

Calculate work done
W = m × g × h
W = 250 × 9.8 × 15
W = 36,750 J
Calculate power
P = W / t
P = 36,750 / 10
P = 3,675 W
P = 3.68 kW
Answer:
The motor’s power is approximately 3.68 kW
