Mechanical Engineer Board Exam Result March 2010






The Professional Regulation Commission (PRC) successfully administered the March 2010 Mechanical Engineering board examination to the qualified examinees. It was held last Saturday and Sunday, March 27 and 28 respectively. This new schedule is actually a month earlier than the previous one. The exam is divided into three main categories or topics, Mathematics (Economy, Laws, and Engineering Sciences), Machine Design (and machine Shop Practices), and Power (Power and Industrial Plant Engineering).

The board of mechanical engineering (BME), as directed by RA 8495 or The Philippine Mechanical Engineering Act of 1998, is the sole body in-charge of making the exam questionnaires. This year’s board members are the following.

Alfredo Y. Po (Chairman)
Vicente B. Vosotros (Member)
Leandro A. Conti (Member)

Board Exam Refresher: Machine Design (Answers)






Here are the answers and solution to the previously posted set of questions in Strength of materials topic.

1. A steel rod 40 mm in diameter 800 mm long cannot extend longer than 41.5 mm. Find the maximum allowable load it can carry in Newtons. E for steel is 200 GPa.
A. 471240
B. 600000
C. 188495
D. 712440

Solution:
Y=PL/EA
P=YEA/L
P=1.5mm (200000N/mm2)(3.1416)(40mm)^2/(4)(800mm)
P=471240N




2. A simply supported beam 3m long has a load of 3KN 1 m from the left support. Calculate the maximum moment.
Mmax=Fab/L
Mmax=3KN(1m)(2m)/3m
Mmax=2KN-m

A. 2.25 kN-m
B. 2.0 kN-m
C. 4.5 kN-m
D. 6.0 kN-m

3. Calculate the maximum deflection of a 12 m beam with fixed ends if the load applied on it is 3KN located at its center. (I=4,200,000 E=200 GPa).
Y=PL^3/192EI
Y=3000N (12,000 mm) ^3/192 (200,000N/mm2) (4,200,000mm4)
Y=32.14 mm

A. 128.6 mm
B. 32.14 mm
C. 0.17 mm
D. 0.27 mm

4. A 40mm short shaft has is rotating at 300RPM. Calculate the power capacity.
For short shafts: (PME Code)
P=D^3*N/38
P-in hp
D-inches
N-rpm
P= (40/25.4) ^3(300)/38
P=30.83hp (0.746hp/kw)
P=23 KW

A. 30.83 kW
B. 23 kW
C. 16.34 kW
D. 10.93 kW
