The car weighs 15kN. The coefficient of static friction between the car tires and the road is \mus=0.5. Determine the steepest grade (the largest value of the angle of \alpha) the car can drive up at constant speed if the car has (a) rear-wheel drive, (b) front-wheel drive, and (c) four-wheel...
Consider the drawing of the lever. Determine the value of the couple, M, so that the resultant of the applied loads passes through the point O. The applied loads include the two forces (400 N, and 320 N), and the couple M.
M=400\times0.15\timescos30+320\times0.3=148(Nm)
Is this equation...
