Angle of Obliquity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Angle of Obliquity = atan(Shear Stress/Normal Stress)
ϕ = atan(𝜏/σ_n)
This formula uses 2 Functions, 3 Variables

Functions Used

tan - The tangent of an angle is a trigonometric ratio of the length of the side opposite an angle to the length of the side adjacent to an angle in a right triangle., tan(Angle)
atan - Inverse tan is used to calculate the angle by applying the tangent ratio of the angle, which is the opposite side divided by the adjacent side of the right triangle., atan(Number)

Variables Used

Angle of Obliquity - (Measured in Radian) - The Angle of Obliquity is the angle made by resultant stress with the normal of the oblique plane.
Shear Stress - (Measured in Pascal) - Shear Stress is force tending to cause deformation of a material by slippage along a plane or planes parallel to the imposed stress.
Normal Stress - (Measured in Pascal) - Normal Stress is stress that occurs when a member is loaded by an axial force.

STEP 1: Convert Input(s) to Base Unit

Shear Stress: 2.4 Megapascal --> 2400000 Pascal (Check conversion here)
Normal Stress: 0.011196 Megapascal --> 11196 Pascal (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

ϕ = atan(𝜏/σ_n) --> atan(2400000/11196)

Evaluating ... ...
