Re: Anna University ECE 3rd SEM Question Bank
You are asking for Question Bank of Anna University so here are paper given in word file & some of its contain described here which is as following
1. Determine the resultant of the three forces F1 = 2.0i + 3.3j – 2.6k; F2 =  i + 5.2j – 2.9k; and F3 = 8.3i – 6.6j + 5.8k, which are concurrent at the point (2, 2, 5.). The forces are in newtons and the distances are in metres. 2. A force F = (6N)i – (3Nj – (4N)k is acting at a point P whose position vector from the origin ‘O’ of the coordinate axes is (8 mm)i + (6 mm)j – (4 mm)k. Find the moment of the force about the origin. 3. State Varignon’s theorem. 4. State the theorems of Pappus and Guldinus to find out the surface area and the volume of a body. 5. State the Coulomb’s laws of dry friction. 6. A belt embraces an angle of 200 over the surface of a pulley of 500 mm diameter. If the tight side tension of the belt is 2.5 kN. Find out the slack side tension of the belt. The coefficient of friction between the belt and the pulley can be taken as 0.3. 7. The motion of a particle in defined by the relation x = t3 – 15 t2 – 20, where ‘x’ is expressed in metres and ‘t’ in seconds. Determine the acceleration of the particle at t = 3 seconds. 8. A mass of 50 kg. has an initial velocity of 15 m/s. horizontally on a smooth surface. Determine the value of horizontal force that will bring the mass to rest in 4 seconds. 9. Define the term ‘coefficient of restitution’ of two bodies under impact. 10. State the principle of conservation of linear momentum of a particle.
