Another benefit of air breaking that wasn't mentioned is that you can hook up a tube to the trailer to use the breaks in the trailer for greater stopping power.
Another point about the torque and horsepower... in a semi the torque curve is such that the engine makes it's maximum torque at idle or slightly above idle. it also makes it's maximum horsepower about the same RPM as your normal driving speed. In a gas engine the maximum torque is usually somewhere above your normal driving RPM and maximum horsepower is at an RPM usually closer to the maximum the engine is rated for. Basically the truck engine always operates in it's power range while a gas engine you have to run it well over normal driving speeds to actually hit the power ratings.
@@amadou65 I think the whole idea of air brakes, whether they are on trucks or trains, is to stop the truck or train if they lose air pressure. This is a safety measure. The brakes on trucks and trains work under the same principle.
The axles with handbrakes have springs holding the brakes on and in the brake chambers (combination chambers) air holds the spring back and therefore the brakes off
How about the truck is the load is gravity free weight out. The contact to the ground is the truck only and wheels, the load is no weight . I'll say removing the weight first before flying. So that i can see , I can defy the load of the truck. The container is Anti gravity way to do it want this pay for my 50years in repair works.

I respect and appreciate Denmark 🇩🇰 love from 🇦🇺

Exactly why adhere to over the speed limit
I was looking for an animated simple explanation of how a semi works and its build! this was really helpful, thanks.
Looking forward to your tractor channel. Brilliant content
As a professional driver myself I never care about the horsepower I care about the torque and plus torque is cooler than horsepower
Love these videos.
👍 thanks
BRAKING...B R A K I N G.

6:47 i wonder if jet fuel will melt those
Spelled braking wrong on the thumbnail, oy.
You spelled OK wrong yourself ( oy )
I thought that compressed air kept the brakes off. I think the absence of compressed air applies the brakes.
This system is set on trains.
