A 2WD tractor with a total weight of 20 kN has a static weight distribution of 25% and 75% at the front and rear axles, respectively. When the tractor is operated on a level ground, the maximum tractive force developed is 10 kN. If external weight of 5 kN is added to the rear axle, neglecting weight transfer, the change in maximum tractive force in kN is
A load of "W" kN is acting on a tyre having 160 mm nominal width. The effective friction coefficient of tyre and ground interaction is "\(\mu\)" and the kingpin offset is 10 mm. Assuming the tyre impression on ground as circle with diameter equal to nominal tyre width, the kingpin torque of the tyre in N.m will be
A pair of straight teeth spur gears is transmitting power at 600 rpm and the pinion has 21 standard full depth involute teeth of module 7 mm. The pitch line velocity of the pinion is
A spark ignition engine is idling at 500 rpm. If the average flame speed is 10 \(m\cdot s^{-1}\) and the flame front must travel 50 mm from the spark plug to consume 85 % of the fuel-air mixture, how much spark advance is needed if 85 % of the fuel is to be consumed before the crankshaft reaches 10\(^\circ\) after HDC?
An engine has a swept volume of 275 \(\text{cm}^3\), clearance volume of 25 \(\text{cm}^3\). Its volumetric efficiency is 0.80 and mechanical efficiency is 0.90. The volume of mixture taken in per stroke is
