The 0.1-lb projectile A is subjected to a drag force of magnitude kv2, where the constant k = 0.0002 lb-sec2/ft2. This drag force always opposes the velocity v. At the instant depicted, v = 735 ft/sec, θ = 40°, and r = 330 ft. Determine the corresponding values of r double dot and theta double dot.

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10
