What is the overall weight of the vehicle,where is the center of gravity?
A truck has a wheel base of 2274 cm .The front wheels weigh 7000N and the back wheels weigh 5000N .
What is the overall weight of the vehicle,where is the center of gravity?
please help this question got me stumbled i8 've tried to figure it out but to no avail
You mean noormal reaction from ground on front wheels is 7000 N and on back wheels is 5000 N. In that case weight of the vehicle balances the sum of these two reactive forces and is therefore = 7000 + 5000 = 12000 N.
If its centre of gravity is at a distance x meter from the front wheel, then
7000*x = 5000*(22.74 - x)
=> 12000*x = (5000)*(22.74)
=> x = 9.475 m from the front wheels.
