3. Movie Stunt MATH: The Motorbike Jump
October 23, 2018Star Stuntman
Star Stuntman Monte Perin (pictured) has involved many films, including “Spider-Man,” “Star Trek, “Indiana Jones and the Kingdom of the Crystal Skull” and portraying Arnold Schwarzenegger’s stunt double in “Terminator 3: Rise of the Machines.”
Perhaps his most difficult stunt was landing his Harley in an open boxcar of a moving train for Disney’s 2008 Adam Sandler movie “Bedtime Stories”. In a career of over 25 years Perin has broken “almost everything” including both his arms, legs, knees, feet, ankles, several ribs, his back and his pelvis. See Confessions of a stuntman
Veteran stuntman Evel Knievel (1938 – 2007) was the pioneer of many stunt jumps. Here he is jumping 10 cars and 3 vans in 1973.
His injuries are legendary:

Ramp Design
The angle of the kicker in ramp design can vary from 100 – 700 (See below)
Moto-X Ramp Jump Maths
The Problem?
If the ramp angle is too high, the stunt jumper also goes high, but doesn’t travel very far.
If the ramp angle is too low, the stunt jumper doesn’t stay in the air for very long and therefore doesn’t travel far. (see below0
The stunt jumper wants the OPTIMUM RAMP ANGLE.
……………………………………………………………………………
METHOD 1: TRIGONOMETRY (cos we can)
As any bike nut knows increasing speed at ake off will increase jump distance.
Here is a graph from final gear for speed vs angle to jump 90m.
OPTIMISING RAMP ANGLE
……………………………………………………………………………….
METHOD 2: MORE TRIGONOMETRY
METHOD 1 is approximate (See STEP 1 & STEP 2 above), but as METHOD 2 produces the same ans (See above), it is very useful.

The maths that proves that the 45 degree angle is the angle that produces the maximum distance travelled is quite tricky and involves trigonometry. But this just shows how cool maths can be. See the full calculations here.

Maths is full-on full of humour.
Can you die laughing, sir?
Try these weird death stats.
Or, how about some maths jokes?
Or, how about a Maths Scavenger hunt.
Funny that!
Many maths teachers come up with great ideas so middle school students have fun with maths. Here are a few:
Human Graphs, Charts and Diagrams
How about a human bar graph?
Or a student linear graph?
Find more @ the colab
Or explore geometry through, well, dance?
These students are showing supplementary angles
These students are acting out the concept of complementary angles.

Or, how about the geometry of yoga?
Can you get your leg or knee to make a perfect right angle?
Or how about a Venn Diagram using Hola Hoops?

Or you can measure length using bodies.
How many Smoots long is your football field?
Oliver Smoot is used as a unit of measure in 1962.
Or try measuring the area of your school hallway in bodies!!!!
