Consider the following distribution of objects: a 4.00-kg object with its center of gravity at (0, 0) m, a 9.20-kg object at (0, 6.00) m, and a 440-kg object at (4.00, 03 m. Where should a fourth atest of mass 6.00 kg be placed so that the center of gravity of the four-object arrangement will be at (0, 0) Need Help?
Sir Lost-a-Lot dons his armor and sets out from the castle on his trusty steed (see figure below). Usually, the drawbridge is lowed to a horizontal position so that the end of the bridge rests on the stone ledge. Unfortunately Lost-a-Lot's squire didn't lower the drawbridge far enough and stopped it at 20.0° above the horizontal. The knight and his horse stop when their combined center of mass is d-1.00 m from the end of the bridge. The uniform bridge is! 6.00 m long and has a mass of 2 300 kg. The lift cable is attached to the bridge 5.00 m from the hinge at the castle end and to a point on the castle wall h 12.0 m above the bridge. Lost-a-Lot's mass combined with his armor and steed is 1 200 kg. (a) Determine the tension in the cable. CH (b) Determine the horizontal force component acting on the bridge at the hinge magnitude direction to the night (c) Determine the vertical force component acting on the bridge at the hinge. magnitude magnitude direction upwards
One end of a uniform 3.20-m-long rod of weight F 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 the figure below. The coefficient of static friction between the wall and the rod is ,-0.540. Determine the minimum distance x from point A at which an additional object, wao with the same weight can be hung without causing the rod to slip at point A B
A hungry bear weighing 700 N walks out on a beam in an attempt to retrieve a basket of goodies hanging at the end of the beam (see figure below). The beam is uniform, weighs 200 N, and is 6.00 m long, and it is supported by a wire at an angle of 60.0. The basket weighs 80.0 N. Goodies (a) Draw a free-body diagram for the beam. (Submit a file with a maximum size of 1 MB) Chọn tập không có tộc nào được chọn This answer has not been graded yet. (b) When the bear is at x 1.00 m, find the tension (in N) in the wire supporting the beam and the components of the force exerted by the wall on the left end of the beam T- N F, = N N (c) If the wire can withstand a maximum tension of 775 N, what is the maximum distance (in m) the bear can walk before the wire breaks? mi
A1 450-N uniform boom ate-59.5" to the vertical is supported by a cable at an angle - 30.5 to the horizontal as shown in the figure below. The boom is pivoted at the bottom, and an object of weight m 2 100 N hangs from its top (a) Find the tension in the support cable. 1911.73 x Your response is off by a multiple of ten. KN (b) Find the components of the reaction force exerted by the floor on the boom. horizontal component magnitude KN direction right magnitude direction upward vertical component KN
Two racquetbals, each having a mass of 196 g. are placed in a glass jar as shown in in the figure below. The centers lie on a straight line that makes a 457 angle with the hontal (a) Assume that the walls are frictionless and determine P₁, P₂, and Py -2.74 x P. Your response differs from the correct answer by more than 10%. Double check your calculations. N (b) Determine the magnitude of the force exerted by the left ball on the right ball..
Consider the following distribution of objects: a 4,00-kg object with its center of gravity at (0, 0) m, a 5.20-kg object at (0, 6.00) m, and a 4.40-kg object at (4.00, 0) m. Where should a fourth object of mass 6.00 kg be placed so that the center of gravity of the four-object arrangement will be at (0, 0)7 Need Help? Ma
Sir Lest-a-Lot dons his armor and sets out from the castle on his trusty steed (see figure below). Usually, the drawbridge is lowed to a horizontal position so that the end of the bridge rests on the stone ledge. Unfortunately Lost-a-Lot's squire didn't lower the drawbridge for enough and stopped it at 0-20.0% above the horizontal. The knight and his horse stop when their combined center of mass is 1.00 m from the end of the bridge. The uniform bridge is f 6.00 m long and has a mass of 2 300 kg. The lift cable is attached to the bridge 5.00 m from the hinge at the castle end and to a point on the castle wall h 12.0 m above the bridge.
