The simple pendulum mechanism is a standard
device for testing impact and projectile motion.
When conducting the experiment, place a steel
ball on the platform, move the “bob” to a certain
swing angle, and then release the bob. The bob will swing in
a pendulum motion. When the bob swings towards the platform
and hits the steel ball, the steel ball will fly off of the platform from the
impact. After flying for a period of time, the steel ball will eventually land on
the ground from its own gravity. This is a horizontal projectile experiment.
This device can also provide settings for a shooting elevation experiment.
What methods can be used to hit the ball far?

There is an impact test for car fuel tanks, which is based on the simple pendulum
theory. This is an experiment designed to test the capability of a car’s gasoline tank
to handle being hit by sharp objects.
The simple pendulum impact machine is mounted onto a beam bracket. The beam
is able to move up and down to adjust the location of the horizontal impact. The
fuel tank is installed onto a base that is attached to a track. This track is able to
move forwards and backwards to adjust the fuel tank’s position, utilizing a three-
dimensional space to define the hammer’s hitting point.
A simple pendulum impact machine has a
pointer and a scale to indicate the opening
angle of the hammer. Since the mass of
the hammer is fixed, we can calculate the
hammer’s impact energy by identifying its
opening angle and thus, evaluate the result
from the impact.
