A small grinding wheel is attached to the shaft of an electric motor which has a rated speed of 3600 rpm. When the power is turned on, the unit reaches its rated speed in 5 s. Assuming uniformly accelerated motion, determine the number of revolutions that the motor executes in reaching its rated speed. (Answer: 0 = 150 rev) %3D

The planetary gear train shown in the image below has 16 teeth on the sun and 50 teeth on the planet. The sun is driven by a motor at a speed of 100 revolutions per minute. The ring is stationary. What is the speed of the arm (planet carrier) in units of revolutions per minute? 5 Sun gear Ns 2 # Arm -3-- - Planet gear NR Np 4 Ring gear OM

The max speed for the servo shown is 130RPM when connected to 6V. Assume that the gearbox on your servo is able to output a torque of 1.5 kg-cm while turning at this speed. Using the number of teeth on each gearprovided in the table, determine the torque and rotational speed of the output shaft on the DC motor. HINT: Work backwards from the output shaft and use the equations developed in class that relate the number of teeth to the torque. When working back from the output shaft to gear 7/6, realize that the “torque” transmitted by gear 7 is the SAME as the torque transmitted by gear 6 since they are joined. Then, relate the torque of gear 6 to gear 5 based on their numbers of teeth. Since gears 5 and 4 are actually one piece, the torque in 4 and 5 will be the same (as was the case for gears 6 and 7). Repeat for the other gears, working your way all the way back to the DC motor.

A single-strand roller chain drive connects a 50-hp engine to a lawn waste chipper/shredder, as shown below. As the engine operates at 1000 rpm, the shredding teeth should rotate at 250 rpm. The driven sprocket has 60 teeth. Determine the chain speed.

Q6. Gear and Motor selection: For a 50 Hz supply frequency, the motor speed is 50 revolutions per second. What gearbox is required to step this down to 2 rad s−1 at the pulley wheel? What is the maximum torque to be developed by the motor? Round off your answers to one decimal place. -The gear ratio required is ? - The maximum torque to be developed by the motor is Nm ?

A robotic arm is made of two links. The input link AB describes a full mode of rotation causing link BC to slide along collar C. The angular velocity of link AB is measured to be as 10 rad's in clock wise direction, whereas the angular acceleration is determined as 20 rad's' describing the same direction of the angular velocity. Determine the following: a) The angular velocity of link BC b) The angular acceleration of link BC c) The relative velocity of link BC with respect to the collar. d) The relative acceleration of link BC with respect to the collar. e) The Coriolis acceleration. s t B 1.8 m 30 2 m

Identify which variables are the outputs or how they relate to the outputs. Plug in all possible numbers. Assuming link 2 rotates at a constant rate of 80 rpm CW, determine the velocity of link 6 when link 2 makes a 10-degree angle with the ground (measured as a right hand horizontal)
