Question

A hammer has two pieces: a thin, uniform body (handle of length 3L, and top of length 2L attached at its mid-point to the handle) with total mass m, and a point-mass like “tip” (also mass m). The hammer hangs on the nail at equilibrium; you may assume that the nail is frictionless and has negligible radius. Note: the downward arrow labeled “g” indicates the direction of gravity in the figure below.

body (mass m) 32

A. Draw and label an isolation diagram for the hammer, being sure to include all forces acting on the hammer.

B.  Solve for the angle θ between the handle and the vertical direction, being sure to define any coordinate(s) you use.

C. The tip slips off (but does not otherwise affect the hammer, which remains instantaneously at rest). Just after this happens, what is the vector direction of the angular acceleration of the hammer body around the nail, using the coordinate system shown? Circle your answer below.

Answer 1

Answer: het us calculate the G of uniform body with handle of 32 and Top length 22 Total mass = 6m ... mass of handle. = 33.mom W 3+ 2 K mass of top length = 2 3+ 2 La = mig,+ meget mitma 14 0.91 Sa = 2.1 & Taking moment about o mg x 0.9 & sino - mg & colo = 0 tano = To = 48.012

when tip just slips off mass of handle will rotate The hammer anti clockwise By right hand thumb rule direction of angular acculuration is t i
