TOTAL MARKS: 0

Due Date: 29/05/2017

DON’T MISS THESE Important instructions:

 

      To solve this assignment, you should have good command over first 18th lectures.

      Upload assignments (Microsoft word) properly through LMS, (No Assignment will be     accepted through email).

      Write your ID on the top of your solution file.

      All students are directed to use the font and style of text as is used in this document.

      Don’t use colorful back grounds in your solution files.

      Use Math Type or Equation Editor etc for mathematical symbols.

      Write to the point and avoid from unnecessary explanation. Don’t copy/paste from internet or any other source.

      This is not a group assignment, it is an individual assignment so be careful and avoid copying others’ work. If some assignment is found to be copy of some other, both will be awarded zero marks. It also suggests you to keep your assignment safe from others. No excuse will be accepted by anyone if found to be copying or letting others copy.

*Note: Please note that non graded assignment given for your practice and enhance understanding, your solution will be marked by Instructor with result declare, but marks would not be included in your final grades. On the other hand the marks obtained in graded assignment will be included in final result marks.

 

Question. No: 1

A pendulum consists of a uniform disk with radius 10.0 cm and mass 500 g attached to a uniform rod with length 500 mm and mass 270 g (see figure below). (a) Calculate the rotational inertia of the pendulum about the pivot. (b) What is the distance between the pivot and the center of mass of the pendulum? (c) Calculate the period of oscillation.                                                    Marks =10

have any solution plz

ASSIGNMENT # 2 (PHY101)

STUDENT ID: bc160404071

Solution 1.

 Itot = Iro + Ido = (1/3)*Mr*Lr^2 + [ Idcm + Md*(Rd + Lr)^2 ] 
 PART (a)

 Itot = (1/3)*Mr*Lr^2 + [ (1/2)*Md*Rd^2 + Md*(Rd + Lr)^2 ] 
where the parallel axis theorem has been used to get the moment of inertia 
Ido of the disk about the pivot point O. Substituting the values 
Mr = 270 g = 0.270 kg

 Lr = 500 mm = 0.5 m

Md = 500 g = 0.500 kg , 
Rd = 10 cm = 0.10 m

we get

Itot = 0.205kg*m^2 
ANSWER: 0.205 kg*m^2 

PART (B) 
The position of the center of mass relative to the pivot point O is given by

Ycm = [ Mr*(Lr/2) + Md*(Lr +Rd) ] / [ Mr + Md ] 
Substituting the values, we get

Ycm = 47.7 cm 
ANSWER:Ycm= 47.7 cm

PART (C) 
The period of oscillation of a physical pendulum is given by 
T = 2*π*sqrt [ I /(M*g* D ) ] 
where D is the distance of the mass M from the axis of rotation and I is 
the moment of inertia of the disk about the axis of rotation. Substituting 
the values

 I = 0.205 kg*m^2

M = 0.770 kg

D = Ycm = 47.7 cm 
we get

 T = 1.53 s 
ANSWER: 1.53 s

………….

SOLUTION  2.

a)1.  A flow in which the velocity of the fluid at a particular fixed point does not change with time also called stationary flow.

a)2. If at any point in the fluid, the conditions change with time, the flow is described as Unsteady Flow.

a)3. Compressible fluid (gas dynamics) is that deals with flows having significant changes in fluid density. Gases mostly display such behavior.

a)4. incompressible fluid (isochoric flow) refers to a fluid in which the material density is constant within a fluid.

a)5. The viscosity of a fluid is a measure of its resistance to gradual deformation by shear stress or tensile stress. For liquids, it corresponds to the informal concept of "thickness"; for example, honey has a much higher viscosity than water.

 

 

b) Airplanes fly thanks to lifting force that is generated by the wings. The wings do this by moving forward through the air. All else being equal, the faster the wings move through the air, the greater the lift. 
Flying into the wind causes the wings to move through the air more quickly without increasing the speed of the aircraft in relation to the ground. This means that an aircraft flying into the wing can get into the air more quickly.

 

 

 

 

 

Hey brother what is meant by the non-graded assignment?

means physically u'll not get the marks but the image. :)
