Shear force is a load (pounds, or newtons) in plane of the object which produces shear stress ( pounds per sq inch, or Pascals). Shear force is related to shear stress as STRESS = FORCE/AREA
what the neccecities of shear test of brass & mild steel
The mathematical symbol for shear is the greek letter tau - which is similar to the English letter "t". Shear stress is given in Pascals or Megapascals, as this denotes pressure - force over an area - which then leads to the applied shearing load.
Graphite has low shear strength due to its laminar lattice structure and weak bonding between the layers which allow graphite to slip in layers resulting in low shear strength. - Dr. Aditi Kulshrestha

You might have weakened the bolt, causing it to shear when you run the engine
If it back fires or it gets jammed up it may have shear the key on the shaft under the fly wheel that would put it out of time.
a gas mower i take it, you can bend the shaft, shear the keyway, and twist the shaft,
Shear
wind shear causes the formation of a tornado if you have a strong thunderstorm.
shear
to much stress on the product, there are many types of 'shear' but in its basic form the ammount of stress/preasure on the material causes it to fail
It could be that the shear pin is damaged or bent and the engine is "out of time" when it gets to TDC. The flywheel will have to be removed to get to the shear pin. The shear pin is the aluminum pin that fits in the keyway of the flywheel and the shaft. It is made of aluminum and meant to break, bend, or shear when the mower blades strike a solid object while rotating. The breaking, bending, or shearing of the pin helps prevent the engine from being damaged or at least minimize engine damage at impact.
Shear stress in science is a type of stress in which an object that has a force acting upon it is applied to skew. This causes shear strain, which can change the shape of the object.
Shear stress causes Transform faults, in strike-slip zones of conservative boundaries.

You should use a 30-weight motor oil, NOT a multi-grade such as 10-W-40. Use of multi-grade oil will increase your oil consumption considerably. Check your owners manual, nearly all Briggs engines made in the last 10 years recommend a multi-viscosity oil, namely 10w30. However, if not used below 40 degree temperature's, 30w detergent oil is fine as it is shear stable (will not degrade to a 20w under high heat).
