Mechanics is a branch of physics concerned with the action of forces on bodies. Engineers of all disciplines use the concepts explored in this unit to design machines, structures, appliances and products...
Let's solve a problem on limits Find limit: x→0 (1 - cos2x ) /(x²) On direct substitution we get 1 - 1/0 = 0/0 which is in indeterminate form Let's substitute (1 - cos 2x ) = 2 sin²...
Fluid is anything which can flow.They are not capable of resisting the shear deformation cause to it because of the shear forces. Both Gases And Liquids studied under fluid. Now come viscosity: Viscosity...
Let us assume a member with uniform cross section A and of lenth l, be subjected to external axial load W as shown in the figure. As the load is gradually applied the load is incresed from 0 to W, due...
