Just as force produces acceleration, torque produces angular acceleration in a body. For a body about a given axis, the angular acceleration is directly proportional to applied torque and for a given torque, it is inversely proportional to moment of inertia of body. In this respect it can be called, Newton’s second law for rotational motion about a fixed axis. The work done by the torque changes rotational kinetic energy of the body.Q. Due to steady pull the angular speed of cylinder at any time is 6 rad/s, starting from rest. What is work done on the cylinder? (mass of cylinder = 20 kg, radius = 20 cm)
प्रश्न - किसी समय पर नियत खींचाव के कारण विराम से प्रारम्भ होने वाले बेलन की कोणीय चाल 6 rad/s है। बेलन पर किया गया कार्य क्या है? (बेलन का द्रव्यमान = 20 kg, त्रिज्या = 20 cm)
