a mixture of 0.64 x 100 percent iso-octane and {1-0.64} x 100 percent methanol, based on volume, is mixed with air and combusted. Calculate the stoichiometric air fuel ratio. Note: please not this is mixing on a molar basis, not mass basis. It is necessary to perform a...
Ques: A disk brake consists of a 5.3 inch radius rotor and a 2 piston caliper, with each piston having a diameter of 1.1 inches. If the brake pad has a surface area of .5 square inches and a friction coefficient of .37, calculate the brake gain, in inch-lbf/psi. Note: the definition of a...
A vehicle has a vertical cg height of 20.5 inches, a wheelbase of 108.5 inches, a wheel radius of 12.11 inches, and a total weight of 4074.0 lbf. 57.7 percent of the weight is on the front wheels and both the front and rear brakes have the same gain of 20.0 in-lbf/psi. Assuming the front and...
A 6 speed standard transmission has a 6th gear ratio of 1:1. if the first gear ratio is 4.86:1, calculate the 4th gear ratio, based on a geometric progression. Answer must be expresses as a single number, two decimal places.
A vehicle with a weight of 3000 lbf is accelerating at .7 gs in first gear. The vehicle shifts from first to second at 1721 rpm (speed before shift). If the final drive ratio is 3.56, first gear transmission ratio is 3, and second gear transmission ratio is 2.4, calculate the engine speed in rpm...
