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?
When visiting some countries, you may see a person balancing a load on the head. Explain why the center of mass of the load needs to be directly above the person's neck vertebrae.
A 15.0-m uniform ladder weighing 500 N rests against a frictionless wall. The ladder makes a 60.0 angle with the horizontal. (a) Kind the horizontal and vertical forces the ground exerts on the base of the ladder when an 800-N firefighter has climbed 4.00 m along the ladder from the bottom. (b) If the ladder is just on the verge of slipping when the firefighter is 9.00 m from the bottom, what is the coefficient of static friction between ladder and ground?
Two children push on opposite sides of a door during play. Both push horizontally and perpendicular to the door. One child pushes with a force of 17.5 N at a distance of 0.600 m from the hinges, and the second child pushes at a distance of 0.450 m. What force must the second child exert to keep the door from moving? Assume friction is negligible.
Why are the forces exerted on the outside world by the limbs of our bodies usually much smaller than the forces exerted by muscles inside the body?
In order to lift a shovelful of dirt, a gardener pushes downward on the end of the shovel and pulls upward at distance l2 from the end, as shown below. The weight of the shovel is mg and acts at the point os application of F2 . Calculate the magnitudes of the forces F1 and F2 as functions of l1 , l2 , mg, and the weight W of the load. Why do your answers not depend on the angle that shovel makes with the horizontal?
One end of a uniform 4.00-m-long rod of weight Fg is supported by a cable at an angle of = 37 with the rod. The other end rests against the wall, where it is held by friction as shown in Figure P12.23. The coefficient of static friction between the wall and the rod is s= 0.500. Determine tile minimum distance x from point A at which an additional object, also with the same weight Fg can be hung without causing the rod to slip at point A.
A cook holds a 2.00-kg carton of milk at arm's length P8.19). What force FB must be exerted by the biceps muscle? (Ignore the weight of the forearm.) Figure P8.19
Consider the person lifting a heavy box with his back, shown in Figure,The mass of the upper body is 55.0 kg and the mass of the box is 30.0 kg.Calculate the magnitude of the force FB –in the back muscles that is needed to support the upper body plus the box and compare this with his weight.
A large airplane typically has three sets of wheels: one at the front and two farther back, one on each side under the wings. Consider the Boeing 787 "Dreamliner", with a mass of 198000 kg. In this particular model, the distance from the front wheels to the rear set of wheels is 23.8 m. a) If the center of mass of the airplane is along a line through the center and 3.00 m in front of the rear wheels, how much force, in meganewtons, does the ground exert on each set of rear wheels when the plane is at rest on the runway? b) How much force, in meganewtons, does the ground exert on the front set of wheels?
A kawayan is 6.0m long and weighs 80 N. It is supported at its center. Anadditional 160N weight is now placed on its left end. To maintain balance, the support mustbe moved by ______ to the left. Choices: 6.0m 2.0m 1.5m 0.50m 1.0m Show complete solution and free body diagram
A hungry 728-N bear walks out on a beam in an attempt to retrieve some ``goodies'' hanging at the end (see figure). The beam is uniform, weighs 216 N, and is 5.41 m long; the goodies weigh 82 N. When the bear is at ?=1.00x=1.00 m, find (b) the tension on the wire and (c) the magnitude of the beam's force on the wall. (This will be equal and opposite to the wall's force on the beam. Both ?x- and ?y-components will contribute.) what is Tension on the wire the Beam's force on wall. If the wire can withstand a maximum tension of 900 N, what is the maximum distance the bear can walk before the wire breaks?
