Show work if any equations or calculations are used.What is the main alloying element and carbon percentage of SAE-AISI 4621 Steel?
The particle has a mass of 0.5 kg and is confined to move along the smooth
horizontal slot due to the rotation of the arm OA. Determine the force of the rod
on the particle and the normal force of the Isot on the particle when 0 = 30°.
The rod is rotating with a angular velocity of ė = 2rad/s and an angular
acceleration of = 3rad/s². Assume the particle only contacts one side of the
slot at any instant. To check your answer, please enter the normal force of the
slot onto the particle in Newtons.
