ENGINO STEM40 Building Blocks for Kids sku-2386694279

ENGINO STEM40 Building Blocks, SKU sku-2386694279, are simple-machine construction toys for kids 9+. The levers and linkages module explores how fulcrum position and linkage geometry affect force and the paths traced by mechanisms such as the Peaucellier-Lipkin and Hart straight-line linkages.

Wheels, axles and inclined planes introduce gradient, friction and the conversion of rotation to linear motion. Pulley drives let learners compare fixed, movable and multi-pulley systems by speed ratio, weight and effort. Cams and cranks show how rotation becomes reciprocating motion and back again, as in oil pumps and sewing machines.

Gears and worm drives cover gear ratio, direction, torque and speed. Each module includes a booklet with theory, experiments and quizzes, plus printable and online instructions and 3D app support.
