A thin structural column of a building, with a size of 2X4 inches, has a load carrying capacity of 636 pounds. Structural engineers subjected the column to a load of 800 pounds, which was beyond its yield point load. The column showed a deformation in the form of a bend from one end. What would engineers refer to this effect as? A.
compression
B.
buckling
C.
tensile
D.
discontinuation

Asimple speed reducer is composed of 2 spur gears. the pinion gear has a pitch diameter of 0.75" and 36 teeth while the driven gear has a pitch diameter of 4.0" and 192 teeth. a)-what is the diametral pitch of each gear? b)-if an electric motor rotating ccw at 3000 rpm is coupled to the pinion, what is the rotational speed of the driven gear? c)-if the torque delivered to the pinion is 1 n-m, what is the torque on the driven gear? d)-what is the power transmitted by the gear train?
