(5) The 400 kg cylinder is attached to the right-angle boom OAB which is supported by three cables and a ball-and-socket joint at O on the wall as shown. The weight of the boom is negligible. Determine the tension in each cable and the magnitude of the reaction at O. Ans: TBD = 2770 N, TAC = 4810 N, TBE = 654 N, 0 = 6830 N 1 m 0.75 m B 0.75 m 400 kg 1.5 m. 2 m 1 m 1 m E

The diameter of a carousel merry-go-round is 30ft. At full speed, it makes a complete revolution in 6 s. At what rate, in feet per second, is a horse on the outer edge moving?

Solve these prism and cylinder exercises. Where necessary, round the answers to 2 decimal places unless otherwise specified. A solid brass casting in the shape of a right circular cone has a base diameter of 4.36 inches and a height of 3.94 inches. Find the weight of the casting. Brass weighs 0.302 pound per cubic inch.

Solve these prism and cylinder exercises. Where necessary, round the answers to 2 decimal places unless otherwise specified. A solid right cylinder 9.55 centimeters high contains 1910 cubic centimeters of material. Compute the cross-sectional area of the cylinder.
