Two wheels with fixed hubs, each having a mass of 1kg , start from rest, and forces are applied: F1= 1 N to the first wheel and
irina [24]

Answer:

2N

Explanation:

m = m_1 = m_2 = 1 kg

The torques generated by tangential forces on the 2 wheels are

T_1 = F_1R_1 = 1*0.5 = 0.5 Nm

T_2 = F_2R_2 = F_2*1 = F_2 Nm

According to Newton's 2nd law, the angular accelerations generated by these torque would be

\alpha_1 = \frac{T_1}{I_1} = \frac{0.5}{mR_1^2} = \frac{0.5}{1*0.5^2} = 2 rad/s^2

\alpha_2 = \frac{T_2}{I_2} = \frac{F_2}{mR_2^2} = \frac{F_2}{1*1^2} = F_2 rad/s^2

For the 2nd wheel to have the same angular acceleration, its force must be

\alpha_1 = \alpha_2

2 = F_2

F_2 = 2N
