Note that the water tank load may be idealised as a point load. Please also note that there are also other types of loads, which should be considered for practical design, but for simplicity they are not considered here.A 75 mm x 150 mm beam carries a central load P over a 1.2 m span. Square notches 25 mm deep are provided at the bottom of thebeam at the supports. Calculate the load P based on shear alone. Allowable shear parallel to grain= 1.40 MPaAllowable shear normal to grain= 1.85 MPa
