What Does Tie-Rod Hole Mean?
A tie-rod hole is a hole left in a concrete structure after removal of the tie rods used in the concrete formwork. After construction, these holes are typically patched using hydraulic cement or another acceptable material. While tie rod holes do not significantly affect the overall strength of the finished concrete structure, they are known to be the cause of leaks, particularly in foundations or basement walls.

How to tell if tie rod is bad?
The unbalancing of the steering wheel is one of the most common symptoms of a bad tie rod end. Due to a bad rod, the steering wheel couldn’t properly handle the vehicle wheel, and it became unbalanced. You can easily observe this sign when you try to steer the vehicle wheel.
What is the tie rod end?
The tie rod end is a most important component of the vehicle’s steering system. The tie rod links the pinion gear and steering gear with the vehicle wheel by using a section of the rod with a ball socket at one end. The tie rod end transfers the power from the rack gear or the steering center link to the steering knuckle.
What happens if you loosen your tie rods?
The loose failed or damaged tie rods may cause the “toe out” of the tires, which may cause misalignment of the vehicle. When driving a vehicle with “toed out” tires, the inside of the tire tread wears out faster over time.

What is a tie rod?
A tie rod is a device that links your car’s steering knuckle to the steering rack on the front wheel. The out and inner ends of the tie rid surround an adjusting sleeve. When you rotate your steering wheel, it activates movement throughout the mechanism. The rods pull or push the wheel and make it turn. Since you’ll find it virtually impossible to drive your vehicle if you can’t turn the steering wheel, it doesn’t take long to realize just how vital the maintenance of your tie rods can be.

What are the signs to look for that your car might have failing tie rods? First, keep a watchful eye on the wear and tear to your tires. If the tread on your front wheels seems to be wearing out faster than the remainder of your tread, this could mean that your wheel camber is off kilter.
Where is the tie rod on a brake rotor?
You should be able to locate the tie rod at the back of the hub and brake rotor so you can perform a visual inspection for damage. Torn bushing should indicate that something like road debris or grit gathered and corroded it, which would require a full replacement. If the bushing looks good, take hold of the outside tie rod and shake it to see if it moves. If the tie rod sways between sides, you need to replace it.

Overview
Physics and engineering principles
In general, because the ratio of the typical tie rod's length to its cross section is usually very large, it would buckle under the action of compressive forces. The working strength of a tie rod is the product of the allowable working stress and the rod's minimum cross-sectional area.
If threads are cut into a cylindrical rod, that minimum area occurs at the root of the thread. Often rods are upset (made thicker at the ends) so that the tie rod does not become weaker when thre…

Geometry
Osgood and Graustein used the rectangular hyperbola, its conjugate hyperbola, and conjugate diameters to rationalize tie rods at 15 degree radial spacing, to a square of girders, from its center. The tie-rods to the corners (45°) correspond to the asymptotes, while the pair at 15° and 75° are conjugate, as are the pair at 30° and 60°. According to this model in linear elasticity, the application of a load compressing the square results in a deformation where the tie rods maintai…
