1) A ladder whose length L is 12 m and mass m are 45 kg rests against a wall. Its upper end is a distance h of 9.3 m above the ground. The center of mass of the ladder is one-third of the way up the ladder. A fire fighter whose mass M is 72 kg climbs the ladder until his center of mass is halfway up. Assume the wall but not the ground is frictionless. What forces are exerted on the ladder by the wall and by the ground? Provide both the magnitude and direction of the ground and wall forces.
Solutions
Expert Solution
In order to find the force due
to wall and ground we have to consider the torque about a point and
then we have to consider the net force in x and y direction

A beam of length L and mass M rests on two pivots. The first
pivot is at the left end, taken as the origin, and the second pivot
is at a distance , from the left end. A woman of mass m starts at
the left end and walks toward the right end. When the beam is on
the verge of tipping, find symbolic expressions for (a) the normal
force exerted by the second pivot in terms of M, m,...

A uniform ladder of length L and mass m leans against a
frictionless vertical wall, making an angle of 57° with the
horizontal. The coefficient of static friction between the ladder
and the ground is 0.42. If your mass is four times that of the
ladder, how high can you climb before the ladder begins to
slip?
