Answer:
Force on front axle = 6392.85 N
Force on rear axle = 8616.45 N
Explanation:
As we know that the weight of the car is balanced by the normal force on the front wheel and rear wheels
Now we know that
now we know that distance between the axis is 2.70 m and centre of mass is 1.15 m behind front axle
so we can write torque balance about its center of mass
now from above equation
now we have
now the other force is given as
A person walks up a flight of stairs √
Wind lifts a balloon into the air √
A weightlifter holds a barbell straight overhead √
Gravity is used in most real world examples because if not of gravity everyone would be floating all around ^-^
