A nonuniform ladder is leaned against a frictionless wall. The ladder has a mass of 30 kg, a length of 10.0 m, and makes a 60° angle with the ground. The coefficient of static friction between the ladder and the ground is 0.42. Assume g = 10.0 m/s^2 a. If a 75 kg firefighter is able to climb 90% of the way up the ladder before it begins to slip, where is the center of mass of the ladder located...

The left-hand end of a slender uniform rod of mass m is placed against a vertical wall. The rod is held in a horizontal position by friction at the wall and by a light wire that runs from the right-hand end of the rod to a point on the wall above the rod. The wire makes an angle θ with the rod. a)What must the magnitude of the friction force be in order for the rod to remain at rest?...
One end of a uniform 3.80-m-long rod of weight Fg is supported by a cable at an angle of θ=37° with the rod
One end of a uniform 3.80-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=0.580. Determine the minimum distance x from point A at which an additional object, also with the same weight Fg' can be hung without causing the...
A Pivoting Rod on a Spring - (full respect) help..
A slender, uniform metal rod of mass and length is pivoted without friction about an axisthrough its midpoint and perpendicularto the rod. A horizontalspring, assumed massless and with force constant , is attached to the lower end of the rod, withthe other end of the spring attached to a rigid support.(a) We start by analyzing the torques acting on the rod when it isdeflected by a small angle from the vertical. Considerfirst the torque due to gravity. Which of the...
