Design load factor for (a helical gear is smaller than that for (a straight tooth spur gear because
A. Load concentration factor may be same in both but dynamic load factor is smaller in (i)
B. Both load concentration factor and dynamic load factor are smaller in (i)
C. Load concentration factor is smaller even though dynamic load factor may be higher in (i)
D. Load concentration factor is smaller in (i) even as the dynamic load factor is the same for both
