The exact same thing as the first drive axle.
No. Depending on how you use the wheel and axle changes what type of lever it is. If the wheel is turning the axle it is a second class lever. If the axle is changing the wheel, it is a third class lever.
A dump truck with two (tandem) rear pulling axles supported by a third fixed axle located in the middle of the truck which only reaches the ground after a certain amount of load weight.
You mean third axle. There'll be some sort of switch on the vehicle somewhere.. it may be in the cab, or it could be outside of the cab.
Truck scales have two main purposes for being used. First, sales and charges can be made by having the truck weight on the scales. Second, it checks axle weight and gross vehicle weight, which can prevent some fines.
It's a dump truck with four axles--the steer axle in front and three axles in back. One of them moves up and down via a control in the cab, so the tires aren't on the road if the truck's not loaded. A tri-axle dump truck carries more weight than a one-axle or two-axle truck.
There's no such thing as a one axle truck. There has to be a minimum of two axles. "Single axle" if a term referring to a truck with only a single drive axle, and doesn't count the steer axle. Same with "tandem axle", "tri axle", "quad axle", and "quint axle".
You need to be more specific about the configuration. Is a single axle straight truck, a tandem axle straight truck, a tandem axle straight truck with additional lift axles, a tractor trailer...?
The axle of the truck broke.
From the center of steer axle to center of rear axle on trailer. If you want just the truck it's the center of steer axle to center of rear drive axle.
To remove the axle shaft, first remove the wheel, and brake drum/rotor. Second, remove the differental cover. Third, remove the bolt holding the spider gear shaft, and remove that shaft. Fourth push inward on the axle shaft to remove the horseshoe clip on the inside. The axle shaft will now pull out.
Those designations actually exclude the steer axle, and only count axles behind the steer axle, so what you're talking about would actually be a truck with two axles - a steer axle, and a single drive axle.
