• Suppose the pulley has mass M and we model it as a cylinder, radius R. Then I = 1 2 MR 2 for the pulley. Torque is needed to accelerate it. 128 Chapter 5 The Laws of Motion Example 5.9 The Atwood Machine When two objects of unequal mass are hung vertically over a frictionless pulley of
• Torque, Pulleys, and Rotational Motion. Directions: On this worksheet you will practice using the basic formulas for torque and the subsequent rotational behavior. omit. Question 1 A pulley of radius R = 28 cm is created from a solid cylinder suspended on a frictionless axle. One end of a cord is wrapped around the pulley's edge while the other ...

Mutilate a doll no flash requiredThe pulley in the figure has radius 0.160m and moment of inertia 0.480kg*m^2. The rope does not slip on the pulley rim. Use energy methods to calculate the speed of the 4.00kg block just before it strikes the floor. The pulley in the figure has radius 0.160m and moment of inertia 0.480kg*m^2. The...Why is duexis so expensiveI G is the "mass moment of inertia" for a body about an axis passing through the body's mass center, G. I G is defined as: I G = ∫r2 dm Units: kg-m2 or slug-ft2 I G is used for several kinds of rigid body rotation problems, including: (a) F=ma analysis moment equation ( ΣM G = I Gα). (b) Rotational kinetic energy ( T = ½ I
