5. Two shafts 30 in. apart, each carrying a four-step pulley, are to be connected by a cross belt. The driving shaft is to turn 180 rpm while the driven shaft is to turn 50, 150, 250, and 600 rpm. The smallest step of the driver is 10 in. in diameter. Find (a) the diameters of all the steps, (b) angle of contact for each pair of pulleys, and (c) belt length. Please explain the solution/answer.
Design a system which determines the speed depending ambient temperature. Display should show current temperature and fan speed.
(Digital 1): This unit will determine the speed of the motor.
• Measure the ambient temperature and determine the whether the fan should spin at high(220v),medium (150v) or low speed high (80v). Send an analogue signal for the speed to the Motor Driver unit. 220, 150 and 80 volts are recommended levels.
• Allow the user to set the temperature bounds digitally for the speed settings.
•Send the current temperature value to the Speed Measurement unit.
