480 ft-lbf First Gear (2.66) Final Drive (3.42) Figure 2 - Corvette Z06 and its transmission schematic. You start by measuring the 60-0 mph braking performance, which is accomplished along 30.56 m. The test weight (including the driver) was found to be 1510.5 kgf. Peak torque (@4800 rpm) 1st gear reduction Axle Torque Thrust Force After the braking test, you are asked to determine the maximum acceleration in the first gear. Consulting the manufacturer, you find out the following technical data: Final drive (differential) reduction Rolling radius of the rear tyres % weight on the rear tyres Table 1 - Technical data for the Corvette Z06 480 lbf-ft 2.66 3.42 0.327 m 65% 1) Assuming the maximum traction capacity of the tyres has been determined in the braking test, CALCULATE the maximum traction generated by the rear tyres in first gear. CALCULATE the available thrust force (i.e. traction) from the torque on the wheels.
An engine of 175 mm bore and 375 mm stroke is governed by hit and miss type governor to 220 rpm. With a fixed setting of the gas supply and ignition advance, indicator diagrams gave the following values of mean effective pressure. Firing, positive loop 5.7 bar, negative loop 0.25 bar; missing negative loop 0.42 bar. When developing 6 kW the explosions were 100 per minute and the gas used was 0.1 m per minute. Calculate the friction power and assuming uniform gas supply per explosion, find the gas consumption per minute at no load.
Q5: Explain the Angular Speed Measurement Devices.
Q2) A flat belt drive system is to be) designed for an application in which the input shaft speed is 1725 rpm, the driven shaft speed is to be approximately 960 rpm, and the power to be transmitted has been estimated as 2.5kW. The driven machine has been evaluated and found to have characteristics of moderate shock loading during operation. The desired center distance between driving and driven pulleys is approximately 0.5m. The recommended pulley diameter is 110mm. The belt is made of polyamid with density of 0.95g/cc and the coefficient of friction is 0.8. The limiting design-allowable tension per unit width for the polyamide is 613ON/m.a. If 5mm-thick belt material were chosen for this application, what belt width would be required?b. What initial tension would be required for ?proper operation
