The figure shows an object of mass ?1 = 1.0 kg on an inclined frictionless surface. The angle of theinclined surface is ? = 25 with respect to the horizontal. The object of mass ?1 is connected by anideal string over an ideal pulley to a second object of mass ?2 = 2.05 kg on a horizontal frictionlesssurface below the overhang that is formed by the inclined surface.

In about 1915, Henry Sincosky of Philadelphia suspended himself from a rafter by gripping the rafter with the thumb of each hand on one side and the fingers on the opposite side. Sincosky’s mass was 79 kg. If the coefficient of static friction between hand and rafter was 0.70, what was the least magnitude of the normal force on the rafter from each thumb or opposite fingers? (After suspending himself, Sincosky chinned himself on the rafter and then moved hand-over-hand along the rafter. If you do not think Sincosky’s grip was remarkable, try to repeat his stunt.)
