Robots with telescoping arms are sometimes used to perform tasks (e.g., welding or placing screws) where access may be difficult for other robotic types. During a test run, a robot arm is programmed to extend according to the relationship r = 3 + 0.5 cos(40) and the arm rotates according to the relationship 0 = - + лt, where r is 4 in feet, is in radians, and t is in seconds. Determine (a) the velocity and acceleration of the robot tip A at t = 3 s and (b) use a computer program to plot the path of tip A in x and y coordinates for 0 ≤ t ≤ 4s. π 2

8.. An air blower is to deliver 40,000 ft3 /min. Two U-tube gages measure suction and discharge pressures. The suction gage reads a negative 2′′ of water. The discharge gage, located 3 ft above the point to which the suction gage is attached, reads +3′′ of water. The discharge and suction ducts are of equal diameter. What size motor should be used to drive the blower if the overall efficiency is 68% (γ = 0.0750 lb/ft3 for air)? indicate free body diagram
(a) A very important component of a system has a mean time between failures of 100 hr and a mean time to repair of 10 hr. Determine the inherent availability of the system. (b) If the equipment in Q7 (c i) above is required to meet an inherent availability requirement of 0.985 and a mean time between failures of 100 hr. Calculate the permissible mean time to repair and if the system as a mean of the time intervals between corrective maintenance actions of 900 hrs and the sum of the mean corrective maintenance time intervals including supply downtime and administrative down time of 10 hrs Determine the operational availability of the system

Scenario 14.1 — Vidalia OnionsWhen Vidalia onions are ready, the entire 13 county (plus parts of seven other counties) area in Georgia where they are grown is devoted to the harvest, packaging and shipping of this delicacy. The Onion Shack currently purchases 120,000 bags of onions each year at a price of $100 per bag (a bag is ten pounds). Onion Shack has historically purchased in lots of 3000 bags. Transit time and capacity vary as indicated in the table (lead time is 2 days more than transit time). The safety inventory that Onion Shack requires is 30% of lead time demand and the holding cost for a bag is 15% of cost. Carrier Quantity Shipped (cwt) Quantity shipped (bags) Shipping cost ($/cwt) Transit time (days) Mashburn Rail 200+ 2000+ $2.10 5 Sylvia Express 100+ 1000+ $2.35 3 Anita Enterprises 250+ 2500+ $1.35 3 Smith Trucking 250+ 2500+ $1.00 3 Use Scenario 14.1 to determine the inventory holding cost of the Anita Enterprises option if the Onion Shack purchases…

C)If both cyclists have 170 mm cranks on their bikes, what will be the mechanical advantage (considering only the movement of the feet with a constant force for walking and riding), in percent, that each rider will have achieved over walking the same distance? (This can be found by dividing the distance wallked by the distance the feet move in riding.)
