Problem 4 A punch press needs to move a stamp downward 2.0 inches in 0.8 seconds and return in 0.4 seconds. Determine the time ratio Q and the crank angular speed w (in rpm). Also, sketch the timing chart and estimate the peak velocity and acceleration. Problem 5 A package is moved at a constant rate from one end of a 20-ft horizontal conveyor to the other end in 16 seconds. Determine the linear speed of the conveyor belt in ft/sec. Problem 6 A gear uniformly rotates 225 clockwise in 1.5 seconds. Determine the angular velocity in rpm and rad/s. Problem 7 A linear motor is programmed to move according to the velocity profile shown. Determine the total displacement during this programmed move. v (in./s) 4 2 t(s) 2 4 6 8 11 Problem 8 Consider the drive roller for the conveyor belt shown. Determine the angular velocity, magnitude and direction, of the roller when the belt operates at 12 fpm (12 ft/min). 20"
