Explanation Given information: The mass flow rate ( Δ m Δ t ) is 5 kg/s. The velocity at C ( v C ) is 20 m/s. Calculation: Draw the free body diagram of the chips as in Figure (1). Find the force excerted on the chips using the relation: ( Δ m ) v A + ∑ F ( Δ t ) = ( Δ m ) v C ∑ F = Δ m Δ t v C Substitute 5 kg/s for Δ m Δ t and 20 m/s for v C . ∑ F = 5 × 20 ∡ 25 ° = 100 N ∡ 25 ° Draw the free body diagram of the shredder as in Figure (2)

The elastic bar from Problem 1 spins with angular velocity ω about an axis, as shown in the figure below. The radial acceleration at a generic point x along the bar is a(x) = ω 2 x. Under this radial acceleration, the bar stretches along x with displacement function u(x).
