Problem 1: You have been hired to design a family-friendly see-saw. Your design will feature a uniform board (mass M= 10 kg, length L = 3.7 m) that can be moved so that the pivot is a distance d from the center of the board. This will allow riders to achieve static equilibrium even if they are of different mass, as most people are.

A uniform ladder 8 meters long and weighing 350 N rest against a smooth vertical wall at an angle of 30° to the wall. A 700-N man stands 6 meters up from the bottom of the ladder. Find the horizontal force necessary at the base to keep the ladder from slipping. please use the end at the top as the reference point.
A 30kg mass is tied to a uniform rod whose mass and length are 80-kg and 8-m, as shown below. The rod is attached to the floor via a hinge and makes an angle of 70° relative to the ground; a massless string is also attached to the rod at the ¼ point of the rod and makes an angle of 20° relative to the horizontal. What tension must be provided by the rope so that the system remains in stationary? If at some point the string breaks, what will be the angular acceleration of the system the instant that the string breaks?
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?
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.
The controlling force curve of a spring controlled governor is a straight line. The weight of each governor ball is 40 N and extreme radii of rotation are 10 cm and 17.5 cm. If the values of the controlling force at above radli are 205 N and 400 N respectively and friction of mechanism is equivalent to 2.5 N at each ball. Find The extreme equilibrium speeds of the governor. (1) The equilibrium speed and coefficienct of insensitiveness at a radius of 15 cm
A loaded governor of the Porter type has equal arms and links each 250 mm long. The mass of eachball is 2 kg and the central mass is 12 kg. When the ball radius is 150 mm, the valve is ful open andwhen the radius is 185 mm, the valve is closed. Find the maximum speed and the range of speed. If themaximum speed is to be increased 20% by an addition of mass to the central load, find what additionalmass is required?

In the situation shown in image, let u be the angle of the slope and suppose there is friction between the cart and the track. You find that if the cart and bucket each have the same weight w, they remain at rest when released. In this case, what is the magnitude of the friction force on the cart? Is it less than, greater than, or equal to w?
