Which of the following constraints would most likely limit the effectiveness of the design of Student 1?
О А.
A limited amount of horizontal space
OB
A ramp that is not steep enough
C.
A time limit of eight hours
Two students must build a device or structure that can lift a
stalled, 1,000-kg tractor up to a mobile 5-meter-high
platform. The only motor available to them can apply a
maximum of 2,000 N, which is approximately enough to lift
a 200-kg weight. The students have varying opinions
about the best method to raise the tractor onto the
platform
Student 1
The best way to raise the tractor onto the platform is to
build a ramp and use the motor to pull the tractor up onto
the platform. The motor will be positioned at the top of the
ramp and connected to the tractor with a cable. The
platform will need to be fixed in place as the tractor will be
pulled up the ramp and straight onto the platform, as
shown in the following diagram (diagram not to scale).
