Find resultant force in magnitude and direction if a particle is acted upon by following forces.
The beam AB of span 12 m shown in Fig. 1 is hinged at A and is on rollers at B. Determine the reactions at A and B for the loading shown in the Fig.


A cantilever of length 2 meters fails when a load of 2 kN is applied at the free end. If the section of the beam is 40 mm×60 mm, find the stress at the failure.
Derive using first principle the equation for calculation of maximum shear stress at a section for a beam with rectangular cross section.
A wooden beam 100 mm wide and 150 mm deep is simply supported over a span of 4 meters. If the shear force at a section of the beam is 4500 N, find the shear stress at a distance of 25 mm above the neutral axis (N.A.).
Draw shear stress distribution diagram for Rectangular, Circular T section and I section.
A simply supported wooden beam of span 1.3 m having a cross-section 150 mm wide by 250 mm deep carries a point load W at the center. The permissible stresses are 7 N/mm² in bending and 1 N/mm² in shearing. Calculate the safe load W.
