A wooden door 2.1 m high and 0.90 m wide is hung by two hinges 1.8 m apart. The lower hinge is 15 cm above the bottom of the door. The center of mass of the door is at its geometric center, and the weight of the door is 260 N, which is supported equally by both hinges. Find the horizontal force exerted by each hinge on the door.
In order to get his car out of the mud, a man ties one end of a rope to the front bumper and the other end to a tee 15 m away as shown below. He then pulls on the center of the rope with a force of 400 N, which causes its center to be displaced 0.30 m, as shown. What is the force of the rope on the car?
A 60 kg uniform board 2.4 m long is supported by a pivot d=80 cm from the left end. How far from the left end should a 41.6 kg child sit so that the board is balanced? Answer: cm
A 60 kg uniform board 2.4 m long is supported by a pivot d=80 cm from the left end. How far from the left end should a 41.6 kg child sit so that the board is balanced?
A 75-kg adult sits at one end of a 9.0 m long board. His 25-kg child sits on the other end. (a) Where should the pivot be placed so that the board is balanced, ignoring the board's mass? (b) Find the pivot point if the board is uniform and has a mass of 15 kg.
A 67.0 kg adult sits at one end of a 10.0 m board, on the other end of which sits his 23.0 kg child. Where should the pivot be placed so the board is balanced if the board has a mass of 12.0 kg? (The board’s center of gravity is at the center of the board.)
Two children of mass 15 kg and 26 kg sit balanced on a seesaw with the pivot point located at the center of the seesaw.If the children are separated by a distance of 3.0 m, at what distance, in meters, from the pivot point is the smaller child sitting in order to maintain the balance? r1 =
A homeowner is trying to move a stubborn rock from his yard. By using a a metal rod as a lever arm and a fulcrum (or pivot point) the homeowner will have a better chance of moving the rock. The homeowner places the fulcrum a distance ?=0.288 mfrom the rock, which has a mass of 465 kg, and fits one end of the rod under the rock's center of weight. If the homeowner can apply a maximum force of 671 N at the other end of the rod, what is the minimum total length ? of the rod required to move the rock? Assume that the rod is massless and nearly horizontal so that the weight of the rock and homeowner's force are both essentially vertical. The acceleration due to gravity is ?=9.81 m/s2.
A beam is connected to the floor by a hinge. A rope is attached to the other end of the beam. The other end of the rope is connected to the ceiling. There is box sitting on the beam (see figure).The angle between the beam and the floor is 8.60 degrees. The angle between the rope and the horizontal is 20.0 degrees. The beam is 4.00-m long and has a mass of 6.80 kg. The box sits a distance of d = 0.620 m from the upper end of the beam and has a mass of 8.00 kg. The tension in the rope is 205.7 N.What is the horizontal component of the force on the beam due to the hinge?
Two children of mass 21 kg and 26 kg sit balanced on a seesaw with the pivot point located at the center of the seesaw. If the children are separated by a distance of 2 m, at what distance from the pivot point is the small child sitting in order to maintain the balance? m
A fulcrum is placed 1.0 m from the edge of a 3.0 m-long wooden uniform plank of mass 20 kg. A weight W is placed at the edge of the short end to balance it. What is the proper amount of weight needed to balance the plank? (Hint: first find the plank's weight and draw its vector in the correct location) 4. W A1.0 m- - 3.0 m 5. Two children are on opposite ends of an 8.00 m-long seesaw that is pivoted in the middle. One child weighs 300. N while the other weighs 200. N. A third child weighing 150. N attempts to hop on and balance the seesaw. How far from the fulerum should she sit?
Batman and Robin are lifting a 196 N uniform board with a length of 2.50 m. Batman exerts 55.0 N at a point 0.500 m from the left end. At what distance from left end of the board should Robin exert so that the board stays in equilibrium condition. (Hint: Use the two conditions for equilibrium in a rigid body)
