INSTRUCTIONS TO STUDENTS
1. Type / write your full name and student number (ID Number) on the top of each page of
your Final Assessment (assignment) answer script (You can put them as “header” of each
page).
2. The Final Assessment (Assignment) will be posted in the e-learning portal as per schedule.
You are given 2 days (48 hours) to answer the Final Assessment (Assignment). You must
submit your answer script through e-learning portal on or before the time and day as per
schedule. However, students may submit their Final Assessment (assignment) answer script
through HCT e-mail in exceptional cases as stipulated in the General Guidelines for students
(Guideline No. 3). Multiple submissions are not allowed.
3. All answers should be computerized in MS Word. However for some courses, answers can
be handwritten on white paper using blue or black ink, scanned and must be submitted.
Answers can also be a combination of computerized and handwritten, as the case maybe,
most especially for courses that require formula or computation/calculations in their
answers
4. This Final Assessment (assignment) is an open assessment, which means you may use
course handout, PowerPoint slides, textbooks and other relevant references including ebooks and internet websites (Masedar, Proquest, etc.). However, proper citation is required.
5. Marks will be deducted / cut for plagiarized work according to the plagiarism policy of the
College.
6. Submission after the allotted time will NOT be accepted. However, kind consideration
could be implemented as long as the processes stipulated in the General Guidelines for
students (Guideline Nos. 6 and 7) are strictly followed.
7. You are required to type your full name, ID number and date below the academic
integrity student declaration. This will be considered as your signature which means
conformance to the student declaration.
If you need more clarification, read the general guidelines for students posted in the elearning portal or feel free to contact your lecturer.
______________________________________________________________________________
Academic Integrity Student Declaration
I hereby declare that all my answers in this final assessment (assignment) are my own original
idea and work except for those that I have explicitly acknowledged with proper citations, the
source of the information. I also understand that plagiarism is an offense that can lead to

Q.8. Observe the figures (a), (b) and (c) as shown below. Axle-A is connected to axleB and they move in the circle with uniform speed. The other end of axle-B is
connected to piston. As the axle completes one circle, the piston moves up and down
in the cylinder and completes one oscillation.
When the axle-A is making 0° with horizontal, the volume in the cylinder above the
piston is 40 Litre and the pressure in the cylinder is 10 atm. If the temperature in the
cylinder is always kept constant for all positions of axle-A, calculate the pressure,
when the axle-A makes 135° with horizontal by showing all your work step by step.
