### Wavy Edges

Due to problems in the manufacture of tinplate coils, the edge of the strip can be slightly longer than the centre. This causes a 'wave' on the wall of the coil but can be rectified by differentially stretching the strip to make the edges flat. Students are required to apply Pythagoras' theorem to find the radius...

### Tin Can Design

Tin cans come in a variety of shapes and sizes. In this activity students consider the net of a tin can, the formula for the total surface area and the formula for the volume of the can. The first problem requires students to express the total surface area as a function of r by eliminating h. The second problem...

### Reduction Mill

The reduction mill reduces the thickness of a strip of steel using a series of rollers, each roller making the steel slightly thinner. The percentage reduction is constant on each pair of rollers. The mathematics used to calculate the actual reduction is similar to that used when calculating compound interest....

### How to make your own hovercraft

This resource shows how you can successfully lift a person off the ground using two cordless leaf blowers, problem-solving skills and some STEM knowledge: the same knowledge and skills that are used to design hovercraft.

forces - Balanced and unbalanced...

### Euler's characteristic

This resource explores how 'Euler's characteristic' has had an impact on many aspects of real-life, from computing to the shape of a football. The has been created by the Royal Academy of Engineering in partnership with Tomorrow's Engineers as a STEM club or STEM Ambassador activity, but can also be adapted by...

### Drinks Cans

Drinks cans are made by stamping out circular discs from a sheet of tin. Given the dimensions of the sheet of tin and the diameter of the circle stamped out, students are required to calculate the wastage and to investigate whether there is a more efficient method. The problem requires students to be able to...

### Coil Feed Line

This problem features a coil of tinplate being stored on a mandrel. In the first problem, students are presented with the diameter of the mandrel, the height from the floor, the width of the coil and the density of the steel. The problem is to calculate the maximum coil weight. A worked solution is included with...

### Flying by numbers

This is one of a set of resources produced in conjunction with the engineering company Arconic. The resources are designed to support teaching of key engineering concepts at both key stage 3 and key stage 4, including the new GCSE in Engineering. This resource focusses on the application of maths in engineering....

### Rocket performance in Bloodhound SSC

This detailed exemplar explores the rocket engine performance in the BLOODHOUND SSC engineering project. It requires student knowledge of physics, chemistry and mathematics when applied in mechanical engineering.

​The resource explains the history of the BLOODHOUND project, the dynamics of...

### Remote Operations

This Institute of Engineering and Technology (IET) DIY Faraday Challenge asks students to work in teams to design and make a prototype device that can be operated remotely to pick up objects and accurately locate them on a given target. Devices such as these are increasingly used in medical engineering...
