Item Description

Features

• For use on any engineering course from foundation to postgraduate
• Flexible and modular, each kit fits onto the work panel for experiments and classroom demonstrations
• Supplied in a hard-wearing storage tray with moulded insert to hold parts securely and a graphical list to help check the kit contents
• Rugged and durable parts for safe ‘hands-on’ experiments, allowing better understanding
• Contains all parts needed for experiments in rotational friction

Sci-tech Wall Mounted Screw Jack: Rotational Friction Model MT 160 demonstrates how rotational friction affects the efficiency of popular machine elements, including a screw jack, a wedge and different bearings.

Sci-tech Wall Mounted Screw Jack: Rotational Friction Model MT 160 This versatile kit is part of a series that allows many experiments using different arrangements of their parts. Students, teachers or lecturers fit the parts of the kit to the work panel to study or show an engineering science topic.

This kit includes a screw jack (or ‘jackscrew’), a wedge
and different bearings. It helps students understand how rotational friction affects the efficiency of popular machine elements and bearing materials. It shows why engineers choose some materials and devices above others for any given application.

Students fit the parts to the work panel and apply effort and load weights to find their relative mechanical advantage and efficiency.

The kit introduces students to key engineering terms such as:

• Mechanical advantage

• Velocity ratio
• Efficiency
• ‘Overhaul’
