About the Components
Large Structures Parts (ME-6974)
The ME-6974 Large Structures Parts set consists of two
Mini Car Photogate Flags, two Couplers for the Coaster
Track, and a set of 24 Track Clips. The Photogate Flags
mount on any Mini Car. When the flag on a moving car
travels through a photogate and interrupts the beam, the
car’s motion can be measured. The Couplers are used to
connect Coaster Tracks together, and the Track Clips are
used to connect a Coaster Track to a PASCO structure.)
Use track clips to connect the Coaster Track to the structure beams. Slide the clip into the channel on the underside
of the track. Move the clip into position and lock it into place with a quarter twist as shown.
Flexible I-Beams (ME-6985)
The Flexible I-Beam Set contains forty-six flexible beams of three different lengths. The flexible beams have the
same lengths as three of the I-beams from the Truss Set Members (ME-6993). The flexible beams allow you to
explore the concept of structural failure. By replacing a #3, #4, or #5 I-beam in a structure with one of the flexible
I-beams you can observe the effect of a load that causes deformation. These I-beams are designed to demonstrate
stress and failure and then return to their original shape once the load is removed.
Please note that the flexible I-beams are a different color (beige) than the other I-beams (light blue).
Structures Rod Clamp (ME-6986)
Use a rod clamp to attach a structure beam to any 12.7 mm (1/2”) diam-
eter rod.
