Functions and uses of simple machines: Terms- effort E, load L, mechanical advantage MA = L/E, velocity ratio VR = VE/VL = dE / dL, input (Wi), output (Wo), efficiency (η), relation between η and MA, VR (derivation included); for all practical machines η 1; MA VR. Lever: principle. First, second and third class of levers; examples: MA and VR in each case. Examples of each of these classes of levers as also found in the human body. Pulley system: single fixed, single movable, block and tackle; MA, VR and η in each case. #staricse #icse #machines #physics #icseboard #icseclass10 #sirtarunrupani Google Sir ICSE - Sir Tarun Rupani = Star ICSE 📱 Join Our Superstar Channels: WhatsApp - https://www.whatsapp.com/channel/0029...
