A beam is supported at two ends and loaded at the middle.What is the expression for teh depression produced at its cenrtre?

A beam is supported at its end points by supports which are 12 metres apart. Since the load is concentrated at its centre, there is a deflection of 3 cm at the centre and the deflected beam is in the shape of a parabola. How far from the centre is the deflection 1 cm ?

What is a cylindrical capacitor? Derive expression for its capacitance?

Name the part of the plant which produces its food? What is the process called?

A beam of length'l' is suported at one end. If W is the uniform load per unit length, the bending moment M at a distance 'x' from the end is given by M =1/2 lx -1/2 Wx^2 Find the point on the beam at which the bending moment has maximum value.
