The crane needs to lift a weight or weights 80 cm. (from the ground to the height of the table).
In lifting multiple weights, the motor must be reversible electrically.
You may hook and unhook the weights manually.
The crane needs to have an arm that extends beyond the table no more than 20 cm. The crane cannot support itself in two locations.
The crane needs to be able to lift its weights without tipping.
You may apply a maximum voltage of 3.0 V to the motor.
You need to
use the provided gear and motor kit.
There will be a friendly competition based on how much mass you can lift in two minutes.
The time for
the string to go down will be included in the timing.
Based on the gearing system (not following the directions) calculate the theoretical gearing ratio.
minimum weight needed to keep your crane balanced. (This is a torque problem.)
