Task 6 An industrial trolley of mass 350 kg is used to transport equipment and materials to a workstation within the R and D section. Initially the trolley is at the top of a 15 m high hill, which is inclined at 10º to horizontal as shown and travelling at 6 m/s before rolling down into the station. On reaching the bottom of the hill, brakes are applied to the trolley to slow it down to 0.25 m/s in 4.5 m. Determine: The braking force that slowed the trolley down The time it takes the trolley to slow down The deceleration of the trolley

As a continuation of the 1st question, let's assume that we find the required engine power P=3 kW while pulling the wagon up in the wagon system in Kardemir. Let's wrap the rope around the drum at v=7 m/s while pulling the wagon up steadily at the desired speed (don't take anything from the 1st question. Just think of it as a continuation). If the revolution of the motor we will buy from the market is n= 2800 rpm, accordingly, the RB=? what should we get the radius of the gear? We want to get the radii of the other gears RA = 96 mm, RD = 151 mm.

As shown in Fig. 10.17, consider the person performing extension movements of the lower leg about the knee joint. The setup of the experiment is described in Example10.4. After a series of computations it is determined that the lower leg was extended from 0 = 0° to 0 = 85° with an average angular velocity of co = 3.3 rad/s. For this system it is also estimated that the angular power generated by the knee extensor muscles during the experiment is P=290 W. Assuming that the mass moment of inertia of the lower leg about the center of rotation of the knee joint is lo = 93 kg m^2, determine: (a) The torque produced by the knee extensor muscles b) The work done by the muscles to extend the lower c) The kinetic energy generated by the knee extensor muscles
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?
