Question:

My assembly team is having a difficult time identifying the difference between two halves of an enclosure during assembly. What can I do to ease the process?

Adding keyholes and pins to the current design will help the assembler identify the difference. This basically creates a male and female design to the two halves. Another option is to create an enclosure design that is mirrored along a plane thus allowing for an enclosure to be made by using two identical halves.

Question:

I have a ball tied to a long piece of string. I spin the ball above my head in a counterclockwise circle. When should I let go of the string if I want the ball to land in front of me. Assume I am facing north.

This is a perfect example of breaking a vector into it's components to understand what is going on. As the ball is spinning in a circle, there's two components if we assume polar components. One vector is in-line with the string and points toward the center of the circle. The second vector is tangential to the circle. This second vector will tell you where the ball will go. So, when the ball is at \$\$0^{\circ} \$\$ or string points east. The tangential vector will point directly north and ball will land in front.

Question:

What do the different parts of an equation represent on a graph? \$\$y = mx + b\$\$

Inactive
Emmanuel F.

The equation is like a box that you can put something inside and a special output is given. "Y" is the output and "x" is the input. "m" and "b" are the functions that are applied to the input. So, "m" is the slope, and is multiplied with "x". This will determine how steep the line will be when graphed. It can be any number value, negative, decimal, fraction, whole numbers. The "b" represents the where the line will cross with the y-axis on a graph. Thus, called the y-intercept. Again, this can any number, negative, decimal, fraction, etc.
