A cat walks along a plank with mass 9.84 kg. The center of mass of the plank is 0.918 meters from sawhorse B. The cat is a distance 1.11 meters from sawhorse B when the plank just begins to tip. What is the mass of the cat?
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 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).

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...

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...
a) A uniform plank 8.00 m in length with mass 50.0 kg is supported at two points located 1.00 m and 5.00 m, respectively, from the left-hand end. What is the maximum additional mass you could place on the right-hand end of the plank and have the plank still be at rest? b) The rear wheels of a truck support 57.0 % of the weight of the truck, while the front wheels support 43.0 % of the weight. The center...
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...
