please calculate the following in details
A quarry truck has a loaded mass of 150 t and is powered by a hydraulic circuit (conceptually, a diesel motor connected to a hydraulic pump are connected to a motor in each wheel hub. Each motor has volumetric and mechanical efficiencies of 0.9 and 0.92, respectively, and the pump has volumetric and mechanical efficiencies of 0.93 and 0.96, respectively. The truck has 2.5 m diameter tyres and 4 motor wheels, with the load...

Q – 2. A V-belt drive is to transmit 24 kW of power from a 200 mm pitch sheave operating at 1500 rpm to a 600 mm diameter sheave. The distance between the input and the output shafts is 800 mm. The grove angle f = 40° and the coefficient of friction between the belt and the sheave is 0.25. The belt to be used weighs 0.9 kg/m and the allowable tension in the belt is 900 N. How many...

Please answer all PROBLEM 1 A three-litre four-stroke diesel engine develops 12 kW per m3 of free air inducted per minute. The volumetric efficiency is 82 % at 3600 rpm referred to atmospheric condition of 1 bar and 27 oC. A rotary compressor which is mechanically coupled to the engine is used to supercharge the engine. The pressure ratio and the isentropic efficiency of the compressor are 1.6 and 75 % respectively. Calculate the percentage increase in brake power due...

Figure 1 shows the layout of countershaft used to transmit power to a blower through a pulley drive (4-5). Pulley (driving sheave) 4 has a diameter of 125-mm and pulley (driven sheave) 5 has a diameter of 75 mm. Pulley 5 is mounted vertically below pulley 4 (as shown in the figure). Belt tension on the loose side is 20% of the tension on the tight side. A power of 7.5 kW is transmitted via the gear set (2-3) from...
