WebUnit 3: Forging Definition: Forging is a metal working process in which useful shape is obtained in solid state by hammering or pressing metal. It is one of the oldest … WebApr 24, 2024 · Let the friction force F f be positive in the direction up the plane. Then we have: F = m a ⇒ m g sin θ − F f = m a τ = I α ⇒ F f R = 1 2 m R 2 α no slipping ⇒ a = α R The last two equations give F f = 1 2 m a. Plugging this into the first equation gives (5.8.5) a = g sin θ 1 + 1 2 = 2 3 g sin θ Method 2: Energy.
