A uniform plank that is 4.00 m long has a mass of 7.00 kg. The plank...
A uniform beam resting on two pivots has a length L = 6.00 m and mass M = 76.5 kg. The pivot under the left end exerts a normal force nt on the beam, and the second pivot located a distance l = 4.00 m from the left end exerts a normal force nz. A woman of mass m = 56.7 kg steps onto the left end of the beam and begins walking to the right as in the figure...
Suppose a crate of mass 3.0 kg is placed on the plank in the figure below at a distance x = 8.1 m from the left end. If the plank has a mass of 12 kg, find the forces exerted by the two supports on the plank (left support and right support). 3.0 m .0 m
plank plenk ----> 1. [1pt] A professor of mass m= 80 kg is seated on a light harness connected to a rope and pulley system as shown. The professor's feet touch a uniform plank of mass m lank = 20 kg which is supported by a hinge at the wall. A mass M in a light bucket is suspended from the right end of the plank. The professor is a distance ( = 2.10 m from the hinge; the plank...
Suppose a crate of mass 4.0 kg is placed on the plank in the figure below at a distance x = 7.4 m from the left end. If the plank has a mass of 12 kg, find the forces exerted by the two supports on the plank. (Indicate the direction with the sign of your answer.) Left support______N Right support______N
Suppose a crate of mass 8.6 kg is placed on the plank in the figure below at a distance x = 3.3 m from the left end. If the plank has a mass of 12 kg, find the forces exerted by the two supports on the plank.

This question is worth 20 marks Figure 2 shows a decorator's plank, which is 5 m in length, supported on two trestles. The mass of the plank is 37 kg and the mass of the decorator is 70 kg. In order to paint a stairwell the decorator has to position themselves at point A, as shown on Figure 2. To stop the plank tipping, the decorator's assistant attaches weights to a rope at point B Figure 2 The decorator's plank...
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...
A uniform beam (mass M = 64.0 kg and length L = 4.90 m) is supported by two triangular supports that are placed a distance D = 2.94 m apart, as shown below. The left-most support is at the very end of the beam. A person (mass m = 22.0 kg) starts walking at constant speed v along the beam, beginning from some point between the two supports. How close can the person get to the right-most end of the...
A plank of length L 2.000 m and mass M 4.00 kg is suspended horizontally by a thin cable at one end and to a pivot on a wall at the other end as shown. The cable is attached at a height H 1.40 m above the pivot and the plank's CM is located a distance d 0.600 m from the pivot H2 CM d L Calculate the tension in the cable. 29.29N
A uniform plank of mass 5.00 kg and length 3.60 m is supported by vertical ropes at its ends as in the figure below. A 60.0-kg painter is located 0.500 m to the left of the center and an 8.00 kg bucket is 1.00 m to the right of the center. Find the tensions ?1 and ?2 in the ropes.
