A universal column of 6m carries a Point Load of (180+n2) kN centrally at its axis. The column also carries one end of a simply supported beam of 5m with a uniformly distributed load of (15+n1) kN/m over the whole span and a point load of (20+n2) kN at midspan.
The cross section of the column is shown in Figure Q1.
The beam is simply supported centrally by a square bracket, 250mm x 250mm, which is welded to the flange of the column.
(a) Determine the combined stress distribution at the top of the column.
(b) Determine the combined stress distribution at the base of the column if the density of steel is 7200 kg / m3.
Take g = 9.81 m/s2.
What is the Law of Machines? Machines which are used to lift a heavy load are governed by the "Law of machines", which says that the effort to be applied on the machine (p) is

What is Modern view Modern view : It objects tend to remain in their initial state; force is needed to change motion. Resistance to alters in motion is known as inertia.
Hence refractive index µ can be determine by measuring the diameter of Newton's rings first with air and then with the liquid for same value of m.
Resistance measurements: An example of how to make AC voltage measurements is shown in the diagram below. Once again, the red and black test leads are connected to the '+' and
