This causes rapid tire wear, can cause the car to follow cracks in the road and can cause tire temperatures to rise higher than normal due to an increase in friction. Negative Camber will often be greatly increased as well. This results in very heavy inner tire wear on the rear wheels of a car that is heavily loaded or towing.
This can be caused by a sand with too little strength or a pouring velocity that is too fast. The pouring velocity can be reduced by redesigning the gating system to use larger runners or multiple gates. [24] [25] A related source of defects are drops, in which part of the moulding sand from the cope drops into the casting while it is still a ...
Caster causes a wheel to align with the direction of travel, and can be accomplished either by caster displacement or caster angle. Caster displacement moves the steering axis ahead of the axis of wheel rotation, as with the front wheels of a shopping cart. Caster angle moves the steering axis from vertical. [3]
If excessive camber — either positive or negative — is applied, the vehicle's tires will wear unevenly, a condition known as "camber wear". A suspension with excessive negative camber places more load on the inboard shoulder of the tire, causing the inboard shoulder to wear out quicker than the outboard shoulder.
These adjustments are the camber, caster and toe. On some cars, not all of these can be adjusted on every wheel. These three parameters can be further categorized into front and rear (with no caster on the rear, typically not being steered wheels). In summary, the parameters are: Front: Caster (left & right) Front: Camber (left & right)
Zero scrub radius (top) positive scrub radius (center) negative scrub radius (bottom) In an automobile's suspension system, the scrub radius is the distance in front view between the king pin axis and the center of the contact patch of the wheel, where both would theoretically touch the road. It can be positive, negative or zero.
In mechanical engineering, backlash, sometimes called lash, play, or slop, is a clearance or lost motion in a mechanism caused by gaps between the parts. It can be defined as "the maximum distance or angle through which any part of a mechanical system may be moved in one direction without applying appreciable force or motion to the next part in mechanical sequence."
Collapsed barn at Hörsne, Gotland, Sweden Building collapse due to snow weight. Structural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs.
