Problem Solving: Transportation Systems The Activity: Egg Crash Vehicle

Car safety has come along was since Henry Ford’s Model T. Seat belts were invented in1849 by Volvo. As a teenager, I remember seatbelts being first introduced commercially in American cars (that was 1964). Power brakes, air bags, avoidance control systems all make driving in a car safer today. As soon as we get rid of the driver, they will become even safer. Your job is to protect your driver, Mr. Humpty Dumpty.

The Problem: To design and build a vehicle that will carry an egg safely down a wooden ramp and protect it from cracking as it does the following…  Travels further than 33 feet down ramp.  Crashes into brick wall 6 “ from bottom of ramp and leaves the occupant in one piece. The Vehicle

Constraints – Constraints are limitations placed on a problem. They may occur because of costs, availability, of other reasons.

 Width of Vehicle: at least 3 inches but not wider than 7 inches including the wheels.  Length of Vehicle: at least 6 inches but not more than 8 inches  Height of Vehicle: not taller than 4 inches (measured from “ground” to top of roof)  Costs $24.00 or less to build.  You must use school chassis  You may not glue or staple anything to the chassis.

 Print neatly and fill in heading.  Print your seat number in the right corner and circle it (right corner is by scale)  Trace line across paper on white side and label it PLANE LINE.  Trace long skinny box and other box from graph paper side to white side of paper.  Label the right side of drawing as the front of the car. 

 WHEELS - Now take a 1 ½” diameter wheel and draw the front and back wheel (the back wheel should be on the right) of  your car in the front view. The center point of the wheels must be located directly UNDER the rectangle in the front view.  Use your pencil and darken the two lines BETWEEN the wheels.  Any part of the rectangle behind the wheels should be drawn with hidden lines.  Use guidelines to draw the front and back edges of the front wheel all the way to the top of the paper. Do the same for the back wheel.  Draw the back wheel in the TOP view. Draw a horizontal line ¼” away from the rectangle connecting the two guidelines in the top view.  Measure ¾” from that line and draw a parallel line.  Connect the two lines. It should form a ¾ x 1 ½ “ rectangle.

 Do the same on the opposite side  Draw the front wheel in the TOP view. Draw a horizontal line ¼” away from the rectangle connecting the two guidelines in the top view.  Measure ¼ ” from that line and draw a parallel line.  Connect the two lines. It should form a ¼ x 1 ½ “ rectangle.  Do the same on the opposite side.  Darken in the wheels.  Use guidelines to extend the center point of both wheels to the top edge of paper.  AXLES (optional)- Connect the two pair of wheels with two parallel lines 1/8 “ apart. Use the guideline as the centerline. Where the lines go under the rectangle they are hidden, where they can be seen they are solid.  FRONT VIEW  Draw the front view as seen from the passengers side of car.  Any place in the front view where a line forms an angle, usea guide line to extend that point into the top view.  TOP VIEW  Use the guidelines to locate lines in the top view.  DIMENSIONS – Add 5 dimensions to your drawing..  Darken in all object lines.  Erase all guide lines and other marks.  Hand in.
