m

A two hinged arch of span $40$ m and rise $6$ m carries a bolio uniformly distributed load of $35$ kN$/$m for the left half of the span and a concentrated load of $120$ kN at $10$ m from right support. Assume I $=$ lo sec$),$ lo is the moment of inertia at crown and is the slope at the section under consideration. Determine the
