engineering recuitment GATE ME 2023-24 Test Series Design of Machine Elements Brakes Energy Absorbed by a Brake
A mass of 2500 kg is lowered at a velocity of 1.5 m/sec from the drum as shown in figure. The mass of the drum is 50 kg and its radius of gyration can be taken as 0.7 m and radius of drum is 0.75 m. On applying the brake, the mass is brought to rest in a distance of 0.5 m. Which of the following statements are true?
1
The energy absorbed by the brake is 15124 J
2
The Torque capacity of the brake is 22.7 kN-m
3
The energy absorbed by the brake is 18149 J
4
The Torque capacity of the brake is 17.4 kN-m
