Rotational Inertia of a Point Mass
The purpose of this experiment is to find the rotational inertia of a point mass experimentally and to verify that this value corresponds to the calculated...
Introduction to Structures
This activity explores how parts of the PASCO Structures are assembled.
Introduction to Stepper Motors
This activity explores the control of stepper motors using a //control.Node in preparation for performing sense and control experiments with the Motorized...
Introduction to Servo Motors
This activity explores the control of servo motors using a //control.Node in preparation for performing sense and control experiments with the StructureBOT...
Introduction to the //control.Node
This activity explores all the features of the //control.Node in preparation for performing sense and control experiments with the Motorized Drawbridge,...
Raise the Drawbridge in Response to a Signal
Operate the Drawbridge in response to a signal. The signal comes from the 3-axis accelerometer in...
Using the Load Cell as a Limit Switch
Learn to use a load cell and Blockly code to make the Drawbridge automatically stop when it touches...
Explore the Effect of Gear Ratios
Why does the Drawbridge have an 18-tooth gear driving a 72-tooth gear? What happens if you replace them with different gears? In this investigation you...
Explore the Effect of the Drawbridge Counterweight
Why does the Drawbridge have a counterweight? What happens if you remove it? In this investigation...
Measure Loads in Drawbridge Supports
A rectangular base supports the drawbridge. How do the loads at the front and back corners compare? How do they change as the drawbridge moves up and down?...
