The elevators which are on the tail section are used to control the pitch of the plane. A pilot uses a control wheel to raise and lower the elevators, by moving it forward to back ward. Lowering the elevators makes the plane nose go down and allows the plane to go down.
Explanation:
Answer:
Car has more power output than crane
Explanation:
We have given that mass of the crane m = 1000 kg
Height through which crane lift the steel beam h = 10 m
Acceleration due to gravity 
So work done by crane 
Time period is given as t = 5 sec
We know that power 
Now mass of the car = 1000 kg
Initial velocity u = 0 m /sec
Final velocity v = 10 m/sec
We know that work done is equal to the change in kinetic energy
So work done 

Time ids given as t = 2 sec
So power 
So car has more power output than crane
