In leaf springs, the maximum bending stress developed in the plates is (where W = Load acting on the spring, $$l$$ = Span of the spring, n = Number of plates, b = Width of plates and t = Thickness of plates)

In leaf springs, the maximum bending stress developed in the plates is (where W = Load acting on the spring, $$l$$ = Span of the spring, n = Number of plates, b = Width of plates and t = Thickness of plates) Correct Answer $$\frac{{3{\text{W}}l}}{{2{\text{nb}}{{\text{t}}^2}}}$$

In a ring beam subjected to uniformly distributed load
i) shear force at mid span is zero
ii) shear force at mid span is maximum
iii) torsion at mid span is zero
iv) torsion at mid span is maximum
The correct answer is
A leaf spring consists of 3 extra full length leaves and 14 graduated length leaves. The maximum force that can act on the spring is 70kN and the distance between eyes of the spring is 1.2m. Width and thickness of the leaves are 100mm and 12mm respectively. If modulus of elasticity is 207000N/mm², calculate the initial nip.
