the plane in which three mutually perpendicular stresses act and the resultant of all is purely normal stress . in this plane value of shear stress is zero
If you mean principal palne, it is th e plane of a member where its tension stress is maximum and shear stress zero ( principal stress). It is the highest stress and is often used to compute failure against tensile allowable. Failure will generally occur in the direction of that plane.
strength of material refers to the ability of a material to withstand an applied stress without failure.the material"s strength is dependent on its microstructure.Strength is considered in terms of compresive strength, tensile strength, shear strength,namely the limit states of this strength.The term of strength of materials most often refers to various methods of calculating stesses in structural members, such as beams,columns and shafts.
A characteristic strength is the strength of the material used for design purpose, and is statistically defined by the lower 5% fractile of a bell curve. Compressive strength is a generic term that could refer to anything
to increase the strength of the material and decrease the weight of the material
to increase the strength of the material
The secret to the strength of corrugated cardboard is in the corrugation. The triangular corrugations enhance the strength of the material in the plane vertical to the corrugations. This produces material which is difficult to crush along the lines of the corrugation but which is weak in the opposite plane.

The 'R' principal of recycle are reduse,reuse and recycle of material.
tobacco was a big material
The impedance of plane material is made equal to the impedance of air,in this way the waves sent by radar does not reflect by material of plane and pass through plane and do not come back to radar.That is why,plane remain invisible to radar.This material was invented by a PHD proffesor in UET Lahore Pakistan.
Hercules' principal power is his superhuman strength.
the maximum stress which the material can bear without breaking is called the maximum tensile strength of the material
If you mean principal palne, it is th e plane of a member where its tension stress is maximum and shear stress zero ( principal stress). It is the highest stress and is often used to compute failure against tensile allowable. Failure will generally occur in the direction of that plane.

to find the shear strength of five different papers you use the formula shear stress equals major principal stress minus minor principal stress divided by two. Shear strength of paper depends on what they paper is made from.
