Conservation of Energy

In physics, the rule of the conservation of energy states that energy doesn’t disappear from the atmosphere; instead, it changes its form from one type to another. Energy is one of the most important physical quantities in nature, and it cannot be created or destroyed — only transformed.

Question

5.
The arms of a Porter governor are 300 mm long. The upper arms are pivoted on the axis of rotation
and the lower arms are attached to the sleeve at a distance of 35 mm from the axis of rotation. The load

radius of the balls is 225 mm. What will be the range of speed for this position, if the frictional
resistances to the motion of the sleeve are equivalent to a force of 30 N?

The 180-lb tree surgeon lowers himself with the rope over a horizontal limb of the tree. If the coefficient of friction between the rope and the limb is 0.60, compute the magnitude of the force applied to the rope by the tree surgeon's hands to let himself down slowly. Express your answer in units of lb.
The mechanism shows two identical 2-kg bars that are 0.15 m long each. They are hinged together at the lower ends and are supported at the upper ends by small rollers of negligible mass which roll on a horizontal rail. Determine the steady state angle assumed by the bars when they are accelerating under the action of a constant horizontal force FN. Also, find the forces on the rollers at A and B as well as the reactions at the hinge C. Take the value of the force F is equal to 123.45 Newtons.

A 2.2-kg sphere S is being moved in a vertical plane by a robotic arm. When the angle is 36°, the angular velocity of the arm about a horizontal axis through O is 45 deg/s clockwise and its angular acceleration is 176 deg/s² counterclockwise. In addition, the hydraulic element is being shortened at the constant rate of 550 mm/s. Determine the necessary minimum gripping force P if the coefficient of static friction between the sphere and the gripping surfaces is 0.58. Compare P with the minimum gripping force P, required to hold the sphere in static equilibrium in the 36° position. 1.0 m $ Answers: P= Ps= i i N N
A car and its load weighs 27 kN and the center of gravity is 600 mm from the ground and midway between the front and rear wheel which are 3 m apart. The car is brought to rest from a speed of 54 kph in 5 seconds by means of the brakes. Compute the normal force on each of the front wheels of the car.
3. A 5-kg crate is released from rest at Point A of a 20-kg ramp which is inclined at 40 degrees as shown in the figure below. The lengths of the ramp is 2 m. The interface between the ramp and the ground can be assumed to be frictionless. Use Newton's 2nd Law and the definition of the center of mass to determine the horizontal distance that the ramp has moved when the crate reaches Point B. Neglect the size of the crate. Does your answer depend on the frictional force between the crate and the ramp? e S

For a technology project, a student has built a vehicle, of total mass 6.00 kg, that moves itself. As shown, it runs on four light wheels. A reel is attached to one of the axles, and a cord originally wound on the reel goes up over a pulley attached to the vehicle to support an elevated load. After the vehicle is released from rest, the load descends very slowly, unwinding the cord to turn the axle and make the vehicle move forward (to the left as shown). Friction is negligible in the pulley and axle bearings. The wheels do not slip on the floor. The reel has been constructed with a conical shape so that the load descends at a constant low speed while the vehicle moves horizontally across the floor with constant acceleration, reaching a final velocity of 3.00î m/s. (a) Does the floor impart impulse to the vehicle? If so, how much? (b) Does the floor do work on the vehicle? If so, how much? (c) Does it make sense to say that the final momentum of the vehicle came from the floor? If…
A device consists of eight balls each of mass 0.7 kg attached to the ends of low-mass spokes of length 1.4 m, so the radius of rotation of the balls is 0.7 m. The device is mounted in the vertical plane. The axle is held up by supports that are not shown, and the wheel is free to rotate on the nearly frictionless axle. A lump of clay with mass 0.35 kg falls and sticks to one of the balls at the location shown, when the spoke attached to that ball is at 45 degrees to the horizontal. Just before the impact the clay has a speed 5 m/s, and the wheel is rotating counterclockwise with angular speed 0.26 radians/s.Just before the impact, what is the angular momentum of the combined system of device plus clay about the center C? (As usual, x is to the right, y is up, and z is out of the screen, toward you.)
