A small hoist is mounted on the back of a pickup truck and is used to lift a 500N crate . Determine the force exerted on the hoist by the htdraulic cylinder BC, the reaction at A.
Two slender rods of negligible weight are pin-connected at A and attached to the 18-lb block B and the 80-lb block C as shown. The coefficient of static friction is 0.55 between all surfaces of contact. Determine the range of values of P for which..
how many grams of Na3PO4 will be needed to produce 250 mL of a solution of a solution that has a concentration of Na+ ions of 1.5 M.
xerted on the shaft shown in the figure, which rotates at 1150 rev/min and supports a 10-kip bending force. Use a 1095 HR steel. Specify a diameter d using a design factor of nd = 1.6 for a life of 3 min. The surfaces are machined.
Calculate the mass flow (in slugs/per second) that comes out the exit of the engine. The plane is at standard altitude 50,000 ft and velocity = 2200 ft/s. Would appreciate attack to problem.
what will be the final temperature in the tank? how much work will be accomplished over the course of the entire process?
