An object moves across a level floor on an overhead track system. Calculate the pulling force to overcome inertial and frictional effects, and the horsepower (HP) required by a chain driven motor to move the object at a velocity of \( 40 \mathrm{ft} / \mathrm{min} \). Object is supported by one drive wheel and one idler wheel, each made of steel with a radius of 6 inches. Neglect motor/chain/sprocket inefficiencies. Assume the rolling resistance coefficient is \( 0.002 \). The object weight is \( 6,000 \mathrm{lbs} \). Use dimensions given, as well as the depth of object at 1 foot. The object has the motor mounted to it and is homogenous.
