One end of a uniform ℓ = 4.40-m-long rod of weight w is supported by a cable at an angle of

θ = 37°

with the rod. The other end rests against a wall, where it is held by friction (see figure). The coefficient of static friction between the wall and the rod is

μ_s = 0.595.

Determine the minimum distance x from point Aat which an additional weight w (the same as the weight of the rod) can be hung without causing the rod to slip at pointA.
m

A cable attached to a vertical wall at its left is connected at point B to the right end of a horizontal rod, whose left end is at point A, against the wall and below the string. A weight labeledw hangs from a string at a horizontal distance xto the right of point A. The cable makes an angle θ with the horizontal rod.

1. A rod of uniform density and weight W=120N has length L=1.00 m and is supported at two points, under the 10 cm point and under the 70 cm point. The support at 10 cm exerts a force NL on the rod and the support at 70 cm exerts a force NR on the rod, both forces being in the vertical direction. (a) Use the conditions of static equilibrium to find the values of NL and NR. (b) In order...

A thin 1.5-m-long uniform rod with a total mass of 1650 g is suspended vertically at the upper end. The moment of inertia of the rod in respect to the center of mass is mL2/12 (where L is the total length of the rod). A 12-g bullet is shot to the lower end of the rod and embeds there. The bullet speed before impact is 380 m/s. Calculate the amount of energy transferred to the heat during the collision.
