1.	A force of 400 N is applied to the brake drum of 0.5 m diameter in a band brake system as shown in figure, where the wrapping angle is 180∘. If the coefficient of friction between the drum and the band is 0.25, the braking torque applied, in Nm is
Answer» A force of $400 N$ is applied to the brake drum of $0.5 m$ diameter in a band brake system as shown in figure, where the wrapping angle is $180^{\circ}$ . If the coefficient of friction between the drum and the band is $0.25$ , the braking torque applied, in $N m$ is
