Web28 aug. 2024 · Answer: 2/7 Explanation: => Linear Kinetic energy of a solid spherical ball is 1/2mv² and rotational Kinetic energy of a ball is 1/2Iω² But, I = 2/5mr² ∴ rotational K.E. of ball = 1/2 ( 2/5mr²)ω² =1/5mv² => Thus, total Kinetic energy = Linear K.E. + rotational K.E. = 1/2mv² + 1/5mv² = 5/10 mv² + 2/10 mv² = 7/10mv². Web28 jul. 2024 · Focusing on spherical (circular) balls — such as those used in golf, baseball and basketball —- the size and mass of the ball helps determine how it travels. In addition to having an impact on speed and trajectory, the size and mass of balls also contribute to how external forces affect them.

WebA) Thread/Gear Rolling. The thread/ gear rolling is a cold-forming type of rolling process used to cut gear or threads on a cylindrical blank. In this process, the threaded dies are fitted on cylindrical rollers of the rolling machine. The cylindrical blank presses the threaded roller and roll against the faces, which displace the material and ...
