| -2- Appendix. Weight of B.50 Family Saloon unladen - 36 cwts, = 4032 lbs. Assume weight distribution front and rear to be equal to that of the Wraith C.T.L. - 25-G-VI. which is: Front 2100 lbs. Rear 2154 " Then front and rear weights of B.50 are: Front 1990 lbs. Rear 2042 " If we spring the car for a load in the similar way to that adopted for our present cars with this type of body, we take three passengers of 150 lbs and put 25% on the front and 75% on the rear. We also add 1 cwt of luggage all on the rear. This gives: Front 2102 lbs. Rear 2494 " Assuming the unsprung weight of the rear to be the same as for B.2. i.e. 400 lbs, the rear sprung weight = 2094 lbs. The rear springs would be 1050 lbs. | ||
