### Why do drag race semi trucks slant to one side?

as the engine produces torque which is applied to the driveshaft, the engine block produces a counter-torque which must be blocked by bolting the block to the frame so the engine itself does not ...

### Equal power transmission in 4x4 vehicles?

It depends on what type of differential it has. The nature of an open differential (as found on normal road cars) is that the spinning wheel(s) will get all of the torque. Proper off-road vehicles ...

### Why do drag race semi trucks slant to one side?

Inertia plays a small part, but because the mass of the engine and drive train is low compared to the mass of the vehicle, it is a small torque compared to the torque being transmitted through the ...

### Should I discard part of the data (steel traction test)

all tensile testers exhibit this accomodation range to a slight degree, but in your case the large accomodation range is most likely caused by worn parts in the drive mechanism that pulls on the bar- ...

### How to calculate the maximum starting traction force for a train with multiple carriages?

The answer to the first part of question is, you're right, you don't concern yourself with the other carriages friction or weight. The second part, you have to consider static friction force on the ...

### Can stress tensor be defined on feature edges?

The stress does not make sense at absolutely sharp corners. In reality, the corners will have some radii on which actual stress/strain will depend.

### What is the minimum frictional force required for a vehicle to operate smoothly, retain traction, and prevent any skids?

basically the acceptable coefficient of friction friction requirement is not dependant on mass because the heavier the vehicle is the harder in presses on the road, and so the more it grips. This is ...

### Rotational and translation DoFs in structural mechanics

In the general theory of 3D elasticity, there is no need for rotation variables. However many engineering structures such as shells and beams have one or two dimensions that are small compared with ...

### Should I discard part of the data (steel traction test)

Edit after AgentP's comment: As AgentP pointed out, you have swapped your stress-strain axes in the zoomed image. This fact alone refutes your conjecture... Your graph should look like this: You see ...

### Why do drag race semi trucks slant to one side?

I think your assessment is correct. The rear wheels effectively allow the truck to 'pop a wheelie', i.e. lifting the centre of mass by a certain amount. The frame of these trucks is flexible enough ...

### Equal power transmission in 4x4 vehicles?

Only if the differential is limited slip. If there is no limited slip diff then the wheels with no traction will just spin wildly and no torque is transferred to the wheel with traction. Some off-...
