Is honda better in speed than BMW?
the measure of a force acting on an object that causes that object to rotate basically it is the part of the car that increases speed more torque more speedDoes the SportKa SE have an adjustable steering column?
Torque is a measure of how much a force acting on an object causes that object to move.The object rotates about an axis, which we will call the pivot point, and will label 'O'. We will call the force 'F'. The distance from the pivot point to the point where the force acts is called the moment arm, and is denoted by 'r'. Note that this distance, 'r', is also a vector, and points from the axis of rotation to the point where the force acts. (Refer to Figure 1 for a pictoral representation of these definitions.) Torque is defined asJacked up chevy truck and need to lower head lights, help?
= r x F = r F sin(). mathematically

In other words, torque is the cross product between the distance vector (the distance from the pivot point to the point where force is applied) and the force vector, 'a' being the angle between r and F.Torque is defined as
= r x F = r F sin().
In other words, torque is the cross product between the distance vector (the distance from the pivot point to the point where force is applied) and the force vector, 'a' being the angle between r and F.
Can you have gear drive timing on a 2003 5.3 generation III GM V8 Motor?
Using the right hand rule, we can find the direction of the torque vector. If we put our fingers in the direction of r, and curl them to the direction of F, then the thumb points in the direction of the torque vector.
Just got 20inch rims on my 06 Altima and they are rubbing in the rear what do I do?
Imagine pushing a door to open it. The force of your push (F) causes the door to rotate about its hinges (the pivot point, O). How hard you need to push depends on the distance you are from the hinges (r) (and several other things, but let's ignore them now). The closer you are to the hinges (i.e. the smaller r is), the harder it is to push. This is what happens when you try to push open a door on the wrong side. The torque you created on the door is smaller than it would have been had you pushed the correct side (away from its hinges).
There may be more than one force acting on an object, and each of these forces may act on different point on the object. Then, each force will cause a torque. The net torque is the sum of the individual torques.
I have a 2002 Toyota Rav 4 can some one tell me where is the cheapest place to buy new tyres for it?
Rotational Equilibrium is analogous to translational equilibrium, where the sum of the forces are equal to zero. In rotational equilibrium, the sum of the torques is equal to zero. In other words, there is no net torque on the object.
Note that the SI units of torque is a Newton-metre, which is also a way of expressing a Joule (the unit for energy). However, torque is not energy. So, to avoid confusion, we will use the units N.m, and not J. The distinction arises because energy is a scalar quanitity, whereas torque is a vector. So when the torque from the car engine is high, the car moves faster or asccelerates and vice vaser
Keyless entry code on an 02 ford explorer?? Please help?
torque has nothing to do with speed! in relation to cars they usually give you a figure like 240ft/lbs @ 3000 rpm . this means that an engine with the crankshaft spinning at 3000 revolutions per minute will put out enough work to move 1 pound 240 feet. since no one drives an engine around its basically just a ball park figure because the gearing of your transmission, final drives, differentials, rim diameter and tire profile all change that slightly.All North American Engine builders (all fuels too) base thier torque at the flywheel (horsepower too) but you can get your torque at the wheel by having your car dynometered (dyno'd)
Measurements say lincoln 9inch axle housing?
Cutting through aall that mumbo jumbo now here is a simple rule Torque = Work and when a car works its usually accelerating so the higher your torque at the drive wheel will usually mean higher acceleration speeds.
