Respuesta :

Answer:

W = 17,700 lb

Explanation:

given,

Weight limit of the Bridge = 50,000 lb

Weight of empty truck = 19800 lb

Weight on the back of the truck = 12500 lb

Now,

Total weight of truck + cargo

 = Weight of empty truck + Weight on the back of the truck

 = 19800 + 12500

 = 32300 lb

Weight of cargo which is still allowed.

W = weight limit - weight of the system at present

W = 50000 - 32300

W = 17,700 lb

Weight Truck can still carry is equal to W = 17,700 lb
