A person carries a plank of wood 2.00 m long with one hand pushing down on it at one end with a force F1 and the other hand holding it up at .550 m from the end of the plank with force F2. If the plank has a mass of 20.0 kg and its center of gravity is at the middle of the plank, what are the forces F1 and F2?
A person carries a plank of wood 1.5 m long with one hand pushing down on it at one end with a force F1 and the other hand holding it up at 46 cm from the end of the plank with force F2. If the plank has a mass of 19 kg and its center of gravity is at the middle of the plank, what are the magnitudes of the forces F1 and F2? (The distance of 46 cm is...
A person carries a plank of wood 4.3 m long with one hand pushing down on it at one end with a force F1 and the other hand holding it up at 0.65 m from the end of the plank with force F2 . If the plank has a massof 16.4 kg and its center of gravity is at the middle of the plank, what is the magnitude of the force F1?
A person carries a plank of wood 3.1 m long with one hand pushing down on it at one end with a force F1 and the other hand holding it up at 0.41 m from the end of the plank with force F2 . If the plank has a massof 18.5 kg and its center of gravity is at the middle of the plank, what is the magnitude of the force F1?
A uniform plank of length 2.00 m and mass 34.0 kg is supported by three ropes, as indicated by the blue vectors in the figure below. Find the tension in each rope when a 685–N person is d = 0.500 m from the left end. magnitude of T1 N magnitude of T2 N magnitude of T3 N A person stands on a horizontal 2.00 m long plank a distance d from the left end. The plank is supported by three...
A 9-m long plank of weight 80 N is supported by two vertical posts at the two ends. If a 25-N person stands at 6 m from the right end of the plank. a) The force on the left post is _____ N. b) The force on the right post is ____ N. Suggestion: Draw a sketch to determine forces and torques
A uniform plank that is 4.00 m long has a mass of 7.00 kg. The plank is supported by two sawhorses, one 3.56 m from the right end of the plank and the other 1.50 m from the right end of the plank. A cat of mass 2.63 kg is sitting on the plank at a distance of 1.75 m from the right end of the plank. (a) Draw a free body diagram showing the four forces acting ON the...
torque rotational equilibrium 2. A 10 kg cat walks along a 3 m long plank with a mass of 4 kg that is supported by two sawhorses. The right sawhorse is 0.7 m from the end of the plank. How far from the end of the right sawhorse can she walk before tipping the plank over. 3. Nintendo has designed a new minigame for the next Sonic Party. In the game, players have to balance a rigid body. Where should...
The figure below shows a person fishing with a fishing pole that makes an angle of 20.0° above the horizontal. The distance from the person's hand to the tip of the pole is L = 2.04 m. A fish is on the line, and it pulls the line with a force of F = 115 N at an angle 37.0° below the horizontal. What is the magnitude of the torque (in N · m) exerted by the fish about an...
Two people carry a heavy electric motor by placing it on a light board 2.80 m long. One person lifts at one end with a force of 450 N. and the other lifts the opposite end with a force of 670 N. What is the weight of the motor? Part B Where along the board is its center of gravity located? PartC Suppose the board is not light but weighs 220 N. with its center of gravity at its center,...
