Question

A horizontal rod of length 550 cm is held aloft by friction
against a brick wall on one end and on the other end by a rope of
length 739 cm, which itself is attached to the brick wall directly
above where the rod touches the wall. The coefficient of static
friction between the wall and the rod is 0.549. A ball of the same
weight as the rod hangs from the rod.

What is the minimum distance ball must hang from the wall in order
to the rod to stay stable?

Answer #1

A horizontal rod of length 511 cm is held aloft by friction
against a brick wall on one end and on the other end by a rope of
length 628 cm, which itself is attached to the brick wall directly
above where the rod touches the wall. The coefficient of static
friction between the wall and the rod is 0.524. A ball of the same
weight as the rod hangs from the rod.

A horizontal rod of length 429 cm is held aloft by friction
against a brick wall on one end and on the other end by a rope of
length 584 cm, which itself is attached to the brick wall directly
above where the rod touches the wall. The coefficient of static
friction between the wall and the rod is 0.458. A ball of the same

A bar of length L and uniform density is held horizontally
against a wall by a pivot at one end and a rope of tension T which
pulls up and to the left making an angle \theta with the vertical
wall. The rope is attached to the bar at a distance l = \frac{1}{3}
L from the wall. A mass M is resting at the end of the bar.If the
bar has total mass 2.6kg, the mass M=2.6kg, and the...

One end of a light uniform rod is attached to a wall by a
frictionless hinge. The rod is held in a horizontal position by a
wire that runs from the other end of the rod to the wall. The wire
has length 2.00m and makes an angle of 30.0∘ with the rod. A block
with mass m is suspended by a light rope attached to the middle of
the rod. The transverse fundamental standing wave on the wire has...
