X w₂ = 5 rad/s Kinetic Energy = Angular Momentum H₂ = (provide answer with 4 decimal places) A 15 kg circular disk spins about its axle with a constant angular velocity of ₁ = 10 rad/s. Simultaneously, the yoke to which it is attached is rotating with a constant angular velocity of w2 = 5 rad/s. Determine the angular momentum of the disk about its center of mass O, and its kinetic energy. Note: See lecture Slide 57, Week 10 Wednesday to calculate the mass moments of inertia for a disk. 150 mm i+ w₁ = 10 rad/s j+ J (provide answer with 2 decimal places) k kg.m²/s

Metrology of Screw Threads

Screw threads are a series of ridges having the profile of a helix. This helix profile runs continuously along the length of a uniform solid or a hollow bar of a circular cross-section at periodic intervals. These helix ridges are also formed over a conical bar. These continuous helical ridges are termed threads.
