The leaf blower draws in air at a rate of 400 ft 3 /min and discharges it
Question:
The leaf blower draws in air at a rate of 400 ft3/min and discharges it at a speed v = 240 mi / hr. If the specific weight of the air being drawn into the blower is 7.53(10−2) lb /ft3, determine the added torque which the man must exert on the handle of the blower when it is running, compared with that when it is off, to maintain a steady orientation.

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
