PTU Last Year Papers

Hello Sir I am pursuing B.Tech (CSE) from Punjab Technical University (PTU). I am preparing for 1st semester Exam. My friend told me that last year’s paper was very hard so I want to check its Level. Would you please provide me Last Year Papers of B.Tech (CSE) (1st semester) of PTU so I will get idea about its pattern?

Hii sir, I Wants to get the Question Paper of the B.tech Civil Engineering Subject Strength of Material of the Punjab Technical University ?

As you Asking for the Question Paper of the B.tech Civil Engineering Subject Strength of Material of the Punjab Technical University the Question Paper is given below


Strength Of Materials

Time : 3 Hours

SECTION-A is COMPULSORY consisting of TEN questions carrying TWO marks
each.
2. SECTION-B contains FIVE questions carrying FIVE marks each and students
have to attempt any FOUR questions.

3. SECTION-C contains THREE questions carrying TEN marks each and students
have to attempt any TWO questions

SECTIONA
1. Write briefly :
a) State the limitations of Eulers formula.
b) Define slenderness ratio.
c) Briefly describe distortion energy theory of failure.
d) What is generalized Hookes law?
e) Define a composite bar.
f) What do you understand by an element in a state of simple shear?
g) Define the term obliquity and state how is it determined.
h) What is point of contraflexure?
i) What is neutral axis?
j) Define polar moment of inertia

SECTIONB
2. The ultimate stress for a hollow steel column which carries an axial load of 1.9 MN is 480 N/mm2 . If the external diameter of the column is 200 mm, determine the internaldiameter. Take the factor of safety as 4.

3. Derive an expression for the Youngs modulus of elasticity in terms of bulk modulus.
4. At a certain point in a strained material, the stresses on two mutually perpendicular
planes are 20 N/mm2 and 10 N/mm2 both tensile. They are accompanied by a shear stress of 10 N/mm2

. Find graphically, the location of the principal planes and evaluate
the principle stresses.

5. Explain the concept of a free body diagram with the help of a suitable example.

6. A cantilever 1.5 m long is loaded with UDL of 2 KN/m run over a length of 1.25 m from the free end. It also carries a point load of 3 KN at a distance of 0.25 m from the free end. Draw the SF and BM diagrams of the cantilever
