A 1725 rpm electric motor is to be used to drive a "flat belt" conveyor in a manufacturing facility as shown in the following figure. The conveyor must move "parts" along an assembly line at a rate of 9 ft/s. The roller used to drive the conveyor belt has a diameter of 5 in. A roller chain is used to transfer power from the electric motor to the conveyor drive roller. Answer the following questions based on this information. i.) What is the rotational speed (rpm) of the driven sprocket? ii.) If the "drive" sprocket on the motor has 12 teeth, How many teeth should be on the “driven” sprocket which is connected to the flat belt drive roller (Round to the nearest tooth.)? iii.) If the electric motor is producing 3/4 hp and there is a 5% power loss through the roller chain drive system, what torque (ft lb) does the driven sprocket apply to the shaft of the flat belt drive roller?

Power Transmission Elements

It is defined as the energy transfer from one location to another location. The energy will start moving from the energy generation source to the energy applied position to obtain the work output. From this method, a large amount of electric energy moves from the power station to various electrical substations.

A 1725 rpm electric motor is to be used to drive a "flat belt" conveyor in a manufacturing facility as shown
in the following figure. The conveyor must move "parts" along an assembly line at a rate of 9 ft/s. The
roller used to drive the conveyor belt has a diameter of 5 in. A roller chain is used to transfer power from
the electric motor to the conveyor drive roller. Answer the following questions based on this information.
i.) What is the rotational speed (rpm) of the driven sprocket?
ii.) If the "drive" sprocket on the motor has 12 teeth, How many teeth should be on the “driven”
sprocket which is connected to the flat belt drive roller (Round to the nearest tooth.)?
iii.) If the electric motor is producing 3/4 hp and there is a 5% power loss through the roller chain
drive system, what torque (ft lb) does the driven sprocket apply to the shaft of the flat belt drive
roller?

A piston engine in which the bore and stroke are of equal dimension is referred to as a "square engine". An 8-cylinder square engine has a displacement of 305 in3. What is the bore and stroke? Round to the nearest thousandth of an inch. "bore" is the diameter of a cylinder, and "stroke" is the height of a cylinder (the distance the piston travels in one stroke). You will need the formula for the volume of a cylinder to solve this problem.
