The load on the supports thanks to the bridge itself lb is:
lb =9000 kg × 9.81
m/s=88300N
lb = 9000 kg × 9.81ms=88300N.
The total load due to the truck lt is:
Lt = =3000kg×9.81
m/s =29400N
Therefore, the moments of the truck are:
(29400−y) N×9m on the left support,
(y) N×23m on the proper support,
y = load on the proper support due to the truck
These moments must have an equal magnitude because they rotate in opposing directions. Therefore:
(29400−y) N×9m=(y) N×23m
Thus,
loads of 8270 N on the right support and 21100 N on the left support due to the truck.
44200 N + 8270 N = 52500 N on right.
44200 N + 21100 N = 65300 N on left
The mass may be a physical body's total amount of matter. It also is a gauge for the body's inertia or resistance to acceleration (change in velocity) within the presence of a net force. The degree of an object's gravitational pull on other bodies is additionally determined by its mass.
