This activity is an investigative introduction to class 1 levers. Students create levers and record observations to determine the use and components of a lever.
This is an exploratory activity where students in small groups discover the relationship between the force of resistance, the force of effort, and placement of the fulcrum in a first class lever.
In this 7th grade science lesson, students learn about levers and use them to make-work easier.
(Work in progress!)
Attempted imitations of the 17 projects of LEGO set #9630 (Simple Mechanisms), plus its expansion motor set #9615, but using parts instead from the newer LEGO WeDo sets #9580 and #9585.
WeDo sets may be found in an increasing number of classrooms; they are intended to be introductory robotics sets but include lots of basic mechanism parts and projects.
Good preparation or extension activities for those who have WeDo sets (or perhaps an assortment of "Technic" parts).
This activity is an introduction to the concept of levers, the classes, and their parts using the musculoskeletal system.
In this video segment adapted from NOVA, a team of archaeologists and engineers explores different uses of the lever by recreating the engineering feats of the ancient Easter Island peoples.
This course is the first of a two term sequence in modeling, analysis and control of dynamic systems. The various topics covered are as follows: mechanical translation, uniaxial rotation, electrical circuits and their coupling via levers, gears and electro-mechanical devices, analytical and computational solution of linear differential equations, state-determined systems, Laplace transforms, transfer functions, frequency response, Bode plots, vibrations, modal analysis, open- and closed-loop control, instability, time-domain controller design, and introduction to frequency-domain control design techniques. Case studies of engineering applications are also covered.
