Question 1
A Rectangular plate (denoted as slide in the image) of dimensions 25mmx75mm is placed in a 2D space with the x and y axis as shown in the above picture. It is attached to an xy linear actuation system. The origin is fixed. Two corners of the plate are on the x and y axes when the actuation system is at (0,0). Plate is tilted at 53𝆩 with respect to x at all times.
Part 1: What is the minimum stroke required in both x & y to cover the entire rectangular plate under the field of view of the camera. (The field of view is a point at (100,100))? (Submit the stroke for this problem)
Part 2: At which co-ordinates will you place the camera for the least stroke possible in x and y while still covering the entire plate under the field of view? (Submit the co-ordinates for this problem)
Question 2
A CAM drives a mass up and down when we turn the lever using the lever lifter.
The ratio of the vertical displacement between the mass and the Lever lifting point is 1:10.
In other words, if the lever lifter moves up 'h' distance from a lever horizontal position as shown in the figure, the mass will move up h/10 distance.One way to write this relationship is; x=h/10, where x is the vertical displacement of the mass.
Write another way we can write the above equation using 'theta'.
Question 3
In abowe image,
If l = 2375 mm & p = 37 mm
Part 1: How many holes (n) can be placed symmetrically?
Part 2: Find the general relationship for n as n = f(l, p)
