A 1.6-m-long cantilever beam supports a concentrated load of P= 7.2 kN. The beam is made of a rectangular timber having a widt of 120 mm and a depth of 280 mm. Calculate the shear stress due to the applied load at a point located d = 85 mm below the top surface of the beam.

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and af…
