You construct a version of the cart and bucket, but with a slope whose angle can be adjusted. You use a cart of mass 167 kg and a bucket of mass 57.0 kg. The cable has negligible mass, and there is no friction. What must be the angle of the slope so that the cart moves downhill at a constant speed and the bucket moves upward at the same constant speed? With this choice of angle, what will be the tension in the cable?
In a Proell governor, each ball weighs 2.5 kg; length of each of the main four arms in 20cms, the extended arm is 8 cm long. The pin joints of the main arm are 4 cm from the axis of the governor. For the sleeve to be on its bottom stop the distance between the top and bottom hinge points of the main arms is 30 cm and then the extended arm is vertical. Find the weight of central load when the sleeve just leaves the bottom stop at 150 rpm. What will be the speed of the governor after the sleeve has been raised to 4 cm?

In a four linkages slider mechanism shown in Figure 2, when the crank turn the connecting rod responsible to rising and lowering a weight that riding against incline plane. When the connecting rod lifting the weight, it has to overcome the gravity and the friction force between the weight and the incline plane. On other hand when the connecting rod lowering the weight the friction force will reduces the force on the connecting rod. Therefore the loading on the connecting rod is fluctuating from 9kN to 2 kN. Find a factor of safety of connecting rod against fatigue for infinite life using Goodman theory. Check the first cycle yield factor of safety. The connecting rod is made of AISI1018 CD? A reliability of 90% is desired.
Figure Q1 shows a uniform plank, rests upon a horizontal bench with one end of the bar projecting over the sharp edge of the bench, the bar being at right angles to this edge. The plank is pulled out of horizontally until the centre of gravity overhangs the edge by a distance a, and is then released. The plank rotates about the edge and then slides down.

You have a lever, 2m on each side, and four masses: 5kg, 10kg, 15kg and 20kg. You will place the blocks at different positions on the lever such that the two sides balance. Place each block a unique distance from the fulcrum. Use a torque balance to prove the system will not move.
The forces shown in the following figure act on a specific screwed part. It can be noted that none of them acts directly on the known x and y axes. With this, what should be the force component acting on these axes? Options: a) The force on the x-axis is 20.54 N; and on the y-axis, it is 250.22 N. B) The force on the x-axis is -20.54 N; and on the y-axis, it is 230.22 N. c) The force on the x-axis is -22.54 N; and on the y-axis, it is 190.98 N. d) The force on the x-axis is 21.20 N; and on the y-axis, it is -234.89 N. e) The force on the x-axis is -20.54 N; and on the y-axis, it is 250.22 N.
