- machine theoryarrow_forwardThe flywheel of a small punch rotates at 300 rpm. It is known that 1800 ft - Ib of work must be done each time a hole is punched. It is desired that the speed of the flywheel after one punching be 90 percent of the original speed of 300 rpm. Determine the required moment of inertia of the flywheel. Use the principle of work and energy. (Answer: I = 19.20 lb - ft - s? )arrow_forward1. Determine the angle ” between the table and the plane face of thehemisphere in its equilibrium position, if a solid hemisphere of radius 3m weighing 30kN rests on its convex surface on a level table. A body weighing 3 kN is attached to a point in the circumference of the plane face of the hemisphere. In addition, a force of 5 kN is applied at an angle of 60° from the horizontal level as shown.arrow_forward

His cars use a flywheel to store and supply energy as a means of increasing efficiency. A novice engineer for the company has designed a flywheel system that mounts at the center of mass of the car. The axis of the flywheel is aligned with the y-axis as shown (the coordinate systems for each figure align). If the flywheel is rotating about the base at a constant 120rad/s with a +y sense and the car is traveling in a circular path centered at point C with a constant speed of 20 m/s, solve for parts a) - e). Point G is the center of mass of the car and point F is the center of mass of the flywheel. The base of the flywheel is rigidly attached to the car. All velocities and accelerations should be measured with respect to an inertial coordinate system and reported as vectors with appropriate units. a) Angular velocity of the flywheel G Z Flywheel (back) -y [1 0 0 [I] 0 2…arrow_forwardTo loosen a frozen valve, a force F of magnitude 110 lb is applied to the handle of the valve.
