Question

One end of a uniform ℓ = 3.40-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} = 0.540.

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

Answer #1

Ans : 2.26 m.

One end of a uniform 3.60-m-long rod of weight
Fg is supported by a cable at an angle of
θ = 37° with the rod. The other end rests against the
wall, where it is held by friction as shown in the figure below.
The coefficient of static friction between the wall and the rod is
μs = 0.590. Determine the minimum distance
x from point A at which an additional object,
also with the same weight Fg, can be...

A uniform ladder rests against a frictionless wall at an angle
of
θ = 50.0°
with respect to the ground. If the weight of the ladder is
WL = 250 N,
the length is
L = 9.0 m,
and the coefficient of static friction between the ladder and
the ground is
μs = 0.65,
determine the distance a man with a weight of
WM = 800 N
can climb along the ladder before the ladder begins to slip.

A uniform ladder rests against a frictionless wall at an angle
of θ = 54.0° with respect to the ground. If the weight of the
ladder is WL = 240 N, the length is L = 7.0 m, and the coefficient
of static friction between the ladder and the ground is μs = 0.55,

A uniform ladder of length L and weight w is leaning against a
vertical wall. The coefficient of static friction between the
ladder and the floor is the same as that between the ladder and the
wall. If this coefficient of static friction is μs = 0.370,
determine the smallest angle the ladder can make with the floor
without slipping.

In the figure, a uniform plank, with a length L of 5.19
m and a weight of 586 N, rests on the ground and against a
frictionless roller at the top of a wall of height h =
1.89 m. The plank remains in equilibrium for any value of
θ = 70.0° or more, but slips if θ < 70.0°.
Find the coefficient of static friction between the plank and the
ground.

A uniform horizontal beam with length l= 8.2m and weight W
b= 345N is attached to the wall by a pin connection. Its
far end is supported by a cable that makes an angle of
θ=60° with the beam. Furthermore, a picnic basket of
weight WP= 87N is hanging from the far end of the beam.
The hungry Yogy bear with a weight of WY= 758N is
standing on a beam at a distance d=2.0m from the wall.

A 110 kg uniform beam is attached to a vertical wall at one end
and is supported by a cable at the other end. Calculate the
magnitude of the vertical component of the force that the wall
exerts on the left end of the beam if the angle between the cable
and horizontal is θ = 39°.

A uniform ladder of length l and mass m rests against a smooth,
vertical wall. The coefficient of static friction between ladder
and ground is 0.35. Find the minimum angle at which the ladder does
not slip. (Consider the torques about an axis perpendicular to the
page through O)

An 8.00 m, 201 N uniform ladder rests against a smooth wall. The
coefficient of static friction between the ladder and the ground is
0.600, and the ladder makes a 50.0o angle with the
ground. How far up the ladder can an 801N person climb before the
ladder begins to slip?
