Question

A 5.5 m long ladder with a mass of 10.0 kg is leaning against a wall at a dangerously large angle of 35° (between the ladder and the wall). The coefficient of static friction between the base of the ladder and the floor is 0.50 and the top of the ladder has wheels so there is negligible friction between the ladder and the wall. How far up along the ladder can a 65.0 kg painter climb before the ladder slips?

*Consider center of mass

Answer #1

A 6 m long, uniform ladder leans against a frictionless wall and
makes an angle of 58 ◦ with the floor. The ladder has a mass 26.4
kg. A 68.64 kg man climbs 82% of the way to the top of the ladder
when it slips and falls to the floor. What is the coefficient of
static friction between the ladder and the floor?

A ladder of length 15.0 m and of mass 45.0kg is leaning against
a frictionless building wall. An85.0-kg person standing on the
ladder, 1.00 m from its top end, asks his friend to stand on one of
the lower rungs to prevent the ladder from slipping. If the
friend’s mass is 65.0 kg, where should he stand to keep the entire
system in equilibrium? The coefficient of friction between the
ladder and the ground is 0.300, and the angle that...

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.

A uniform 4m long ladder (ML = 50kg) is leaning against
the wall at 65° above horizontal. There is no friction between the
wall and the ladder but there is friction between the ladder and
the floor. Determine the normal forces on each end of the ladder
and the frictional force on the bottom of the ladder.

A ladder is leaning against a vertical wall, and both ends of
the ladder are at the point of slipping. The coefficient of
friction between the ladder and the horizontal surface is ?1 =
0.115 and the coefficient of friction between the ladder and the
wall is ?2 = 0.153. Determine the maximum angle with the vertical
the ladder can make without falling on the ground.
