B. Polar Coordinates 3. The partial surface of the cam and follower mechanism (used for the motion of intake and exhaust valves in automobiles) is that of a logarithmic spiral r = (40e0.050) in mm, where e is in radians. If the cam is rotating at a constant angular rate of è = 4dd, determine the magnitudes of velocity and acceleration of the follower rod at the instant of 0 = 30°. %3D rad %3D

Completely solve and box the final answers. Write legibly 5. How much twisting moment in lbf-ft is required to drive the shaft of the motor coupled to a pump with a rotational speed of 2,000 rpm. The pump efficiency is 82.0% and can deliver 2,000 gallons per minute of cold water to a height of 200 feet.

Q1. 1) The missile at point A takes off from rest and rises vertically to point B after 6.7 seconds, where its fuel runs out. During this time the acceleration of the missile is a = (C.t) m/s², where C = 3.4 is a constant and tis time in s. (Hint, this expression of acceleration already takes into consideration of gravity.) Then by internal controls the missile tilts to an angle = 40° as shown, while keeping the speed, vg, it has attained, and from there it travels in free flight until it lands on the ground at point D. Determine the missile's height he (in m) at point B. Your answer must include 1 place after the decimal point. Take g = 9.81 m/s². C B hB hc R- D

You are in an inventory management field these days. You are working for a place which works on 365 working days per year. The annual demand is 901 widgets per year.
