Juan draws a free-body diagram of an object that is in dynamic equilibrium moving to the left. A free body diagram with 4 force vectors. The first vector is pointing downward, labeled F Subscript g Baseline = Y. The second vector is pointing right, labeled F Subscript t Baseline = X. The third vector is pointing upward, labeled F Subscript N Baseline = 45 N. The fourth vector is pointing left, labeled F Subscript f Baseline = negative 30 N. The up and down vectors are the same length. The right and left vectors are the same length. Which labels correctly complete the diagram? X: 45 N Y: –45 N X: –45 N Y: 30 N X: 30 N Y: –45 N X: 30 N Y: –30 N

The rigid beam is supported by the three suspender bars. bars ab and ef are made of aluminum and bar cd is made of steel. if each bar has a cross-sectional area of 450 mm2, determine the maximum value of p if the allowable stress is (σallow)st = 200 mpa for the steel and ( σallow)al = 150 mpa for the aluminum. est = 200 gpa and eal = 70 gpa.

One hazard of space travel is debris left by previous missions. there are several thousand masses large enough to detect by radar orbiting the earth, but there are far greater numbers of very small masses such as flakes of paint. calculate the force exerted by a 0.110 mg chip of paint that strikes a space shuttle window at a relative speed of 5.00 ✕ 103 m/s and sticks, given the collision lasts 6.00 ✕ 10-8 s. such a collision chipped the window of the ill-fated challenger in june 1983, causing $50,000 of damage.
