Let's consider a snowplow which is scooping up snow 2 cm deep (d) and the blade is 1 m wide. Lets assume the specific gravity (SG) of snow is 0.2. If we want to plow at 55 km/hr and a 30 degree vertical angle of discharge: (a) what is the force exerted on the blade? (just treat the snow like a fluid of density 200 kg/m^3). (b) what is the power necessary? (c) Suppose with the 30 degree vertical angle of discharge would this change the force exerted on the blade? what would it be if it changes? (It might occur to you that it does little good if we don't angle the blade as we just throw the snow in front of the truck...still in the roadway..)
