If a wooden block of weight W = 9.7 N placed on a smooth surface inclined at .2 an angle 35 and is at rest, then the reaction (F) offered by the surface is y

1.0m 3.0m 0.5m mi m2 PA N, 5. The drawing above shows two objects on a board supported at two locations. The m; = 40 kg (centered over P), m;=20 kg and m3=10 kg. c. Determine the force exerted by N2. (Take torques around P.) d. m2 rolls to the right. Just before the board starts to tip everything is balanced on N2 with no force on N1. Determine how far to the right of N2 m2 could roll without the board tipping. You might find it easier to take torques around a point rather than P.

Q2/. Determine the reactions on the bent rod which is supported by a smooth surface at B and by a collar at A, which is fixed to the rod and is free to slide over the fixed inclined rod. See figure (2). 13.. : ha anto 3 ft -3 ft 200 lb ft 2 ft 12 Fig (2)
