Imagine a board sticking off a cliff. The board has mass M and length L. In order to see into the depths better, you extend the board a distance x over the edge and walk to the end to look down. If you have mass m, what is the maximum distance x you can use before you will tumble into the abyss? 1 The Abyss Hint: To prevent the fall, you have to have the sum of the torques on...
Question 5 P 0.8 m A rigid uniform square block of mass m = 60 kg is resting on the ground as shown above. A force P is applied to the block at 0.8 m above the ground. The coefficient of kinetic friction between the ground and the block is given by uk = 0.2. It can be shown that the free-body diagram for the situation above is as given below, where F is the friction, N is the normal...
5. A uniform beam of mass M- 250 kg and length l- 10.0 m is mounted to a wall by a strong hinge and a cable, as shown. A steel block of mass m = 685 kg is placed on the beam a distance x-2.5 m from the hinge. The cable is at an angle -40°, as shown. a. b. c. d. Calculate the tension in the cable. Calculate the horizontal component of the force the hinge exerts on the...
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...
4.[1pt] A block of mass m - 6.10 kg is released from rest at a height of H- 10.00 m on a curved frictionless ramp. At the foot of the ramp is a sring whose spring constant is k -455.0 N/m. What is the maximum compression of the spring, x? Answer: Submit All Answers 5.[lpt] After the spring reaches its maximum compression, it pushes the block backwards.

In the figure, suppose the length L of the uniform bar is 2.8 m and its weight is 170 N. Also, let the block's weight W = 290 N and the angle θ = 33˚. The wire can withstand a maximum tension of 440 N. (a) What is the maximum possible distance x before the wire breaks? With the block placed at this maximum x, what are the (b) horizontal and (c)vertical components of the force on the bar from...
