Answer:
d. Neither A nor B
Explanation:
Mostly for exhaust bolts we use impact wrenches. Impact wrenches are very useful on flywheels because the crank shaft needs to be fixed from rotating. Also impact wrenches are useful on cars for loosening wheel nuts. The wheels need not to be restrained or the brakes need not to be applied to fiz wheels in position.
Answer:
The given statement for temperature and convection is False.
Explanation:
Convection is not a function of temperature to the fourth power but it depends linearly on temperature. the below equation shows the linear relation of heat transfer due to convection and temperature:
Q = 
Whereas, radiation is a function of temperature to the fourth power.
The Stefan-Boltzmann law gives the relationship between an object's temperature and the amount of radiation it emits. The law is given by:
Answer:
I think option d is the answer
Answer:
the lift equation states that lift L is equal to the lift coefficient CI times the density r times half of the velocity V squared times the wing area A. For given air conditions,shape and inclination of the object, we have to determine a value of CI to determine the lift.
Not really sure but this is all I know
