#1 A bar of mass m and length 2d sits on a peg that is at a distance d from the end of the bar. If a force of F is applied downward at a point d/2 from the end, what is the resulting torque?
a. Fd/2, b.Fd, c. 2Fd, d.3Fd/2
#2 The same bar of mass m of length 2d sits on a peg that is at a distance d/2 from the end of the bar. If a force of F is applied downward at a point d from the end, what is the resulting torque?
?=???+?? or ?=???−?? or ?=???/2+??/2 or ?=?d
#3 If the force from #1 was applied at an angle of 30°, would the magnitude of the torque stay the same, be larger or smaller?

A small block of mass, m, sits on top of a larger block of mass, M. The coefficients of friction between the blocks are μk and μs where μs=3/2μk, but the larger block sits on a frictionless surface. An increasing force, F=ft in the x-direction is exerted on the smaller mass. a) Find the acceleration of larger block and the smaller block in the time before the smaller block slips off the larger block. b) the time in which the...

A lamp of mass M is hung off of a steel bar of mass m and length / (treat as known). The bar makes a M450 60° angle with the vertical wall. In order to prevent the steel bar from bending or snapping, a cable is hung off of the wall that connects at the end of the bar. The cable creates a 45° angle with the vertical wall. 60° a) Draw an extended free body diagram (not for a...

A uniform bar of length 3.7 m and mass 4.8 kg is attached to a wall through a hinge mechanism which allows it to rotate freely. The other end of the bar is supported by a rope of length 5.1 m which is also connected to the wall as shown above. What force in N does the wall exert vertically on the bar through the hinge? (Consider an upward force as positive and a downward force as negative.)

The two uniform bars are identical. The mass and length of each bar are m= 30 kg and L=1.6 m. The top bar rotates around point A, coordinate , locates the bar, and force F(t) = 500 sin 60t (in N) is being applied to the end of the bar. A spring with k = 10000 N/m connects the top bar to a fixed point. The bottom bar rotates around its center at point B and coordinate 0g locates this...
