The elevation of the end of the steel beam supported by a concrete floor is adjusted by meansof the steel wedgesEandF. The base plateCDhas been welded to the lower flange of the beam, and the end reaction of the beam is known to be 18 kips. The coefficient of static friction is 0.30between two steel surfaces and 0.60 between steel and concrete. If the horizontal motion of thebeam is prevented by the forceQ, determine (a) the forcePrequired to raise the beam, (b) thecorresponding forceQ
