Determine the axle loads (normal forces at A, B, and C) for the ore hauler when it is parked on a horizontal roadway with its brakes off. The masses of the cab and the trailer are 4000 kg and 6000 kg, respectively, with centers of gravity at D and E. Assume that the connection at F is equivalent to a smooth pin.
Can it be larger than the largest gas constant in the mixture?
The wind reaches a speed of 27.8 m/s in a storm. calculate the force acting on a 1m x 2m window facing the storm. the window is in a high-rise building. the air density p= 1.2 kg/m3.
A bridge has been constructed between the mainland and anisland. The total cost (excluding toll) to travel across thebridge is expressed as C=50+0.5V, where V is the number of veh/dayand C is the cost/vehicle in cents. The demand for travelacross the..
