TECHNICAL REPORTS – WHY???

“Adolescents entering the adult world in the 21st century will read and write more than at any other time in human history. They will need advanced levels of literacy to perform their jobs, run their households, act as citizens, and conduct their personal lives.”

- Richard Vaca

TECHNICAL REPORTS – THINGS TO LOOK OUT FOR

The most frequent piece of feedback from judges and business partners is that students need to complete all required sections of the report.

The next piece of feedback from judges is that students need to adhere to guidelines such as font type, punctuation, grammar structure, etc.

Your job as coordinator is to proof and guide your students in completing each section appropriately.

While two teams from each school may compete and to some extent their bridges may be similar, the two reports must be original and distinctly

different. If not, then both teams will earn a score of zero.

For FY15 only: The submission of a technical report is required but will be scored on completion only. The technical report will not count towards the

team’s Mousetrap Car score. The submission of a technical report is required for any team to place in the Mousetrap Car Competition.

TECHNICAL DRAWINGS – THINGS TO LOOK OUT FOR

Please review the guidelines and evaluation sheets carefully for new or changed instructions for each event you are entering.

The evaluation sheets may appear similar

between technical drawings but there ARE differences among the criteria.

TECHNICAL DRAWING

EVALUATION SHEET

LINE TYPES • OBJECT LINES: Object lines depict the visible edges of an

object or the edges you would see looking at the object with your naked eyes. They are shown as dark, solid lines. _______________________

• HIDDEN LINES: Hidden lines depict invisible edges inside an object or the edges you would not see looking at the object with your naked eyes. They are shown as dashed lines. - - - - - - - - - - - - - - -

• CENTER LINES: Center lines depict the center of any cylindrical-shaped object whether it be a cylinder or hole. They are shown as a long line followed by a short line, followed by a long line. __________ _ _________

LINES CAN CROSS

DIMENSIONS, THEIR COMPONENTS AND NOTES

• Dimensions tell how far it is from one point on an object to another point. The most basic type is called a Linear Dimension because it gives the straight-line distance from one point to another. There are also Radial, Diameter and Angular Dimensions.

• Dimensions have four basic components: – Dimension Text – Dimension Line and Arrows – Extension Lines – Gap

Notes are added text to describe things on

the drawing. The simplest type is just text, as in the title of the drawing. The other type of note contains a leader, which is an arrow that points to the subject of the note.

The box around the drawing is called the Title Block or the Format.

DIMENSIONS

All Dimensions have 3 parts: • 2 Leaders (or brackets) • 2 Arrows • The dimension with the

units (inches, feet, mm)

leaders

BASIC DIMENSIONING TIPS:

A. Place Dimensions Between Views B. Place smallest dimension nearest

the view being dimensioned

ARROW AND TEXT PLACEMENT

The placement of your dimension lines (arrows) and dimension text depends on the amount of space there is between the extension lines.

3 – VIEW DRAWING

• 3 - View drawings (Working Drawings) are an important part of the engineering process. As a rule, they show an object from three different views (Usually the Front, Top, & Right Side).

• Each of the views are drawn in 2-D (two dimensional) and have dimensions labeling the length, width, and height of the object.
