At gradually (f=w only or m.g) but in sudden there will inertia in addition to it so ( f=w+m.a) then will (f=2w).

Twice stress why & which formula used this it may be more than twice or little less than twice.

Stress do not depend on rate of application of force I prefer equal in both the cases.

Ya. As per the formula. Suddenly applied load doubled than gradully applied load.

Suddenly applied load, having higher velocity compared to gradually applied load.

σ impact load = (F/A)[1 + (1 + 2hAE/FL)^0.5].
What is L in this formula?
What is L in this formula?

Because new load is P=P1+P2, where P1=P2 so the stress is twice.

Here, σ impact load = (F/A)[1 + (1 + 2hAE/FL)^0.5].

In stress it is two times.
In strain it is four times.
In strain it is four times.
