Simple-steps to solving CSWA certification sample questions

"Hello there, I have been going through some of the 2010 CSWA certification sample questions and have made videos that shows simple-steps to solving them. So if you are thinking of getting a CSWA certificate, follow up on this tread. Let's get it on!"

2010 CSWA Practice Question 8: 

Assembly Modeling

Model the assembly shown in the figures provided. Use the following information. The assembly is a scissors lift containing seven components: Lower Base, Upper Base, Link, Pivot, Short Pin, Long Pin, and Shaft. There are two short pins, two long pins, two pivots, and eight links in the assembly.
Unit system: IPS (inch, pound, second)
Assembly origin: As shown
Decimal places: 2
A = 20.50
B = 6.50
C = 36°
Material: AISI 1020 for all components.
Each base has .025″ internal radii.
The shaft is centered in the assembly horizontally (from left to right) and vertically (between the lower base and upper base).
The shaft fits in the holes in the pivot (no clearance).
The pins fit in the holes at the ends of the links and each base (no clearance).
All links are oriented at the same angle (Angle C).
All holes are “through” holes.
What is the center of mass of the assembly with respect to the illustrated coordinate system?
A. X = –1.35, Y = 3.00, Z = 4.25
B. X = –1.35, Y = 3.00, Z = 3.75
C. X = 1.35, Y = 3.00, Z = 3.75
D. X = 1.35, Y = 3.00, Z = 4.25
