|
37680 joules
|
|
|
when gases are compressed, storage tanks should be located as close to the point of use as possible because:

|
|
the English unit for drag resistance is:
|
N/(m/sec)
|
|
|
in the english system of units, why is torque expressed in lb*ft and work in ft*lb
|
it is the way the units fall as the problem is solved
|
|
|
the prime mover in an angular mechanical system is called torque which is determined by multiplying the force applied, by the lever arm. the lever arm is equal to the:
|
radius of the circle in which the force is applied
|
|
|
the length of the radius of a circle measured on the circumference is one:
|
radian
|
|
|
work done by a torque is equal to the torque applied times the:
|
angle moved through
|
|
|
fluid-flow rate units such as "kg per min" or "gm per sec" are units of:
|
mass-flow
|
|
|
an electric motor that is connected to an overhead crane lifts stacks of reinforcement rods. each stack of rods weighs 3000 newtons. how much work is done by the motor if it lifts 5 stacks of rods 50 meters?
|
