Crank and Connecting Rod Apparatus Model MT 012

Sci-tech Crank and connecting Rod Apparatus Model MT 012 is an experimental unit that demonstrates the
conversion of smooth rotary motion into reciprocating motion.
The input angle is set on a ball bearing mounted crank disc made of anodized aluminum and read off on an
angle measuring scale integrated into the base plate. A millimeter scale is fitted for the outlet stroke. The crank
radius can be adjusted in three positions.

Item Description

* Crank drive can be demonstrated either with a fixed or oscillating cylinder

The simple insertion of a bolt enables the swiveling cylinder to be locked, thus a crank drive with either a fixed
or oscillating cylinder can be demonstrated.
The components are attached to a solid, painted base plate. Two handles make the unit easier to carry.
