Strength is the ability to withstand a particular force. There are various different types of strengths and forces to consider but these are the main ones.
Tensile strength
Tensile strength
is the ability to withstand stretching or pulling forces.
Compressive strength
Compressive strength
is the ability to withstand pushing or crushing forces.
Bending strength
Bending strength
is the ability to withstand forces which attempt to bend a material.
Shear strength
Shear strength
is the ability to withstand sliding forces acting against each other.
Torsional strength
Torsional strength
is the ability to withstand twisting forces.
Strength is the ability to withstand a particular force therefore, if a material has good compressive strength, it can resist compressive force.

The following physical properties can also be considered mechanical properties.
The following physical properties can also be considered mechanical properties.
Toughness:
Toughness:
The ability to withstand a sudden impact. Can also refer to a materials ability to withstand bending.
Hardness:
Hardness:
The ability to withstand abrasive wear (indentation or scratching). Tool steel.
Plasticity:
Plasticity:
The ability of a material to be permanently changed in shape by an external force without damage. Many materials display this property which is why plastic materials should be referred to as Polymers.
Malleability:
Malleability:
The ability to withstand deformation by compression.
Ductility:
Ductility:
The ability to be drawn out (stretched).
Aluminium is a good example of a ductile metal. Coke cans. Copper wires are another example.
Elasticity:
Elasticity:
The ability to flex and return to its normal shape when the force is
removed.
