As much as the original purchaser specified in accordance with what's available. You could be looking at anything from a 318 Detroit to a 625 Cat.

The "tandem" part means it has two drive axles, although it is possible for a tandem truck to be a 6x2 vehicle, and have only one of those be a live axle.
It could be either. Tandem simply means that the power unit has two drive axles which operate in tandem. It's common in both articulated and straight trucks.
A semi-tandem truck can typically haul between 26,000 to 34,000 pounds (11,793 to 15,422 kg) on the tandem axle alone, depending on the specific configuration and regulations in the region. The overall weight limit for a semi-truck, including the tractor and trailer, can reach up to 80,000 pounds (36,287 kg) in the U.S. However, these limits can vary based on local laws, the type of cargo, and the vehicle's design. Always check relevant regulations for precise limits.
A typical tandem axle tractor has 6 brake chambers.
Specifics? Tandem, tridem, steel, aluminum, 45', 48', 53'? Generally, you're looking at 15,000 - 19,000 lbs, depending on specifics.
It sounds to me like you're describing a straight truck, rather than a semi-tractor. I'd need to know the model number before I gave you an answer... what you're describing could be either be a single or a tandem axle truck.
Depending on wheelbase, what kind of body is attached to it, etc., it could be anywhere from 13,000 lbs. and up. A daycab semi tractor with a single frame.. you'd be looking between 15,000 and 17,000 lbs. A tandem roll off with an empty 30 yard container and double frame construction, you're looking more in the vicinity of 33,000 lbs. The permitted gross weight for a tandem truck is 54,000 lbs.
I've always heard 10 HP for every 1 ft of implement
The total square footage inside a 53 foot semi trailer is about 3,400 square feet. This space can only be fully occupied if the semi truck and trailer weight combined is 80,000 pounds or less. Federal law regulates how much a loaded semi truck and trailer can weigh. There are also limits on axle weight to arrive at this total. It is 12,000 for steer tires, 34,000 for drives, and 34,000 for tandem axles.
Tandem buggies, also known as double strollers, can vary greatly in price depending on the style and brand name. A Safety First tandem buggy can start at around $150.00. A higher end tandem buggy, such as a Joovy brand stroller, can start at $350.00.
