The Fatigue limit for steel is generally in the region of, compared to the static U.T.S
- 20%-40%.
- 60%-80%.
- 40%-60%.
the correct answer is 40%-60%.
This limiting stress is called the ‘Fatigue Limit’ and for steels, the fatigue limit is generally in the region of 40% to 60% of the value of the static ultimate tensile strength (UTS).

In a single acting propeller, blade angle is increased by
- counterweights and a feathering spring.
- CTM.
- oil pressure.
According my notes, i found out that both single and double acting propeller changes the blade angle using oil pressure. Can anyone explain to me why the answer here says counterweights?
