C-Lever

C-Lever

Procedure 

  • Click C-Lever Worksheet – this must be submitted along with the drawing 
  • You will need to both draw the C-Lever along with dimensions and answer the questions on the worksheet.
  • Follow the tutorial below to determine the methods to answer the worksheet questions.
  • When completed print out both the drawing and this sheet and hand them in stapled together. 

Tutorial Section

Begin the drawing with the center of Circle A at 7.000, 3.375

You need to change the drawing units precision to the needed accuracy.

  • The worksheet shows answers accurate to 4 decimal places therefore you need to change the precision to 0.0000
  • To change precision go to the Application icon pull-down menu, select Drawing Utilities and select Units.

Click C-Lever Worksheet – this must be submitted along with the drawing

 

1. The total area of the C-Lever with all three holes removed is?

  • Command: PEDIT join all the outside of the object into one polyline – see the Titleblock if you don’t remember how to do this)
  • Command: AREA 
    • Command: Add —- Object
      • Select the polygon
    • Command: Subtract —- Object
      • Select the circles to subtract

2. The total distance from the center of circle (A) to the center of circle (B) is?

  • Command: Dist
    • Select the center of (A) then (B)

3. The angle formed in the X-Y plane from the center of circle (C) to the center of circle (B) is?

  • Command: Dist
    • Select the center of (C) then the center of (B)
    • See the X-Y plane

4. The delta X-Y distance from the center of circle (C) to the center of circle (A) is?

  • Command: Dist
    • Select the center of (C) then the center of (A)
    • See Delta X= ____ Delta Y= ____   Delta Z= 0.0000

5. The absolute coordinate value of the center of arc (D) is?

  • Command: ID
    • Select the center of (D)
    • See X= ____  Y= ____  Z= 0.0000
  • If you didn’t begin the drawing with the center of Circle A at 7.000, 3.375 then you will need to move it there.

6. The total length of line (E) is?

  • Command: Dist
    • Select each endpoint of line (E)

7. The total length of arc (F) is?

  • Command: Explode
    • Select the polyline to break up again to its individual parts.
  • Command: Pedit
    • Select the arc (F) and right-click to say “Y”es to changing it to a polyline.
  • Command: List
    • Select the arc (F)
