A locomotive semi-elliptical laminated spring has an overall length of 1.3 m and sustains a load of 78 KN at its center. The spring has 2 full length leaves and 10 graduated leaves with a central band of 105 mm width. All the leaves are to be stressed to 455 MPa, when fully loaded.The ratic of the total spring depth to that of width is 4, E = 210 KN/mm^2. Determine :

Question
A locomotive semi-elliptical laminated spring has an overall length of 1.3 m and sustains a load of 78 KN at its center. The spring has 2 full length leaves and 10 graduated leaves with a central band of 105 mm width. All the leaves are to be stressed to 455 MPa, when fully loaded.The ratio of the total spring depth to that of width is 4, E = 210 KN/mm^2. Determine : 1. The thickness and width othi the leaves. * t = 16.987 mm, b = 64.90 mm t = 18.965 mm , b 63.35 mm O t= 20.44 mm, b = 61.32 mm 2. The initial gap that shoulde be provided between the full length and graduated leaves before the band load is applied * C = 12.61 mm C = 15.36 mm C = 14.03 mm
