# Steel ball function in physics

• newtonian mechanics - Why do the steel balls in a spinning

Nov 24, 2020 \$\begingroup\$ @BobD In the inertial frame the wall exerts a centripetal force on the ball (which is the horizontal component of the normal force). Via Newton's 3rd law, the ball exert an equal but opposite force on the wall, which also is a normal force. I would not categorise this as a centrifugal force since that force generally is considered acting on the ball and not

• Balls, Stainless Steel - Kimball Physics

Details. Stainless steel plates may be positioned using spherical balls (BA parts). Balls allow closer hole alignment than rods, and generate structures which are inherently resistant to twisting. Balls have the disadvantages, however, of being considerably more expensive, harder to assemble, and less flexible with regard to plate spacing

Sep 04, 2020 Rigid Body Example in Physics: A ball bearing made of hardened steel is a good example of a rigid body. Now, drop a ball bearing on a polished marble floor — it’ll bounce just about as well as a Superball. Why’s that? Because, though it is a rigid body, it has near-perfect elasticity.
