A diagonal bar CD was welded to the AB beam supported at its ends. Two perpendicular inertias, each with the value P, are applied to the bar ends, providing a pair of forces. Moreover, a vertical force Q acts on the beam. Determine the reaction of supports A and B. Do not let go of the dead weight of the beam and the bar. Given: P = 200N, Q = 100N, l = 2m, r = 1m, a = 0.5m
Correct RBY = - 75N, RA = 175N

Aplane travels 1000 miles in 5 hours .what is the planes average speed?

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.
