Re: Prist University Model Question Paper

As you are looking to download model question paper of B.Tech 1st Semester Course of Prist University, so here I am providing model question paper:

Prist University B.Tech 1st Semester ENGINEERING MECHANICS Question Paper:

PART A

1. a) Define equilibrium of motion. Write the equations for equilibrium. (2M)
b) State the Laws of friction. (2M)
c) Define centroid and centre of gravity. (2M)
d) State the Parallel axis theorem. (2M)
e) Write the equations of translation. (2M)
f) Explain pappus theorem. (2M)
g) State work-energy theorem for a system of particles. (2M)

PART B
2. a) What are the laws to add two forces and several concurrent, coplanar forces?
Explain in detail. (8M)
b) A block weighing 100 N is resting on a rough plane inclined 200 to the horizontal. It is acted upon by a force of 50N directed upward at angle of 140 above the plane. Determine the friction. If the block is about to move up the plane, determine the co-efficient of friction.(6M)
3. a) State and prove Lamis Theorem. (7M)
b) Five strings are tied at a point and are pulled in all directions, equally spaced, fromone another. If the magnitude of the pulls on three consecutive strings is 70N, 40N and 55N respectively, find graphically the magnitude of the pulls on two otherstrings, if the system is in equilibrium. (7M)
4. a) Differentiate between centroid and centre of gravity. (7M)
b) Find the centroid of the Z section shown in Figure 1. (7M)
5. a) Find the moment of inertia of shaded area shown in Figure 2, below about centroidal axes. (7M)
b) Find the mass moment of inertia of a hollow sphere with respect to a diameter if the mass per unit volume of the material is ρ and the outer and inner radii are Roand Ri, respectively.
(7M)
6. a) The weight of a body on earth is 980N. If the acceleration due to gravity on earth is 9.80m/s2 , what will be the weight of the body on i) The moon, where gravitational acceleration is 1.6m/s2 and ii) The sun, where gravitational acceleration is 270 m/s2. (7M)
b) A bullet of mass 80gm and moving with a velocity of 200 m/s is fired into a log of wood and it penetrates to a depth of 8cm. If the bullet moving with the same velocity were fired into a similar piece of wood 5cm thick, with what velocity would it merge? Also find the force of resistance assuming it to be uniform. (7M)
