I want to select 3 alterative for force sensor plats so the main function of it is that can measure real life-time and send the data to the computer. the force sensor plates should be available on the market to buy it also the size should be not big, the leg press machines plate are 52cm * 65cm and we will divide it to have two single leg press with size 32.5 cm width * 52 cm length. so the size need to be qualify. Also it need to take a high force of 200 kg max. and after selecting the 3 alternatives you need to do a decision matrix with design criteria and from that we see the perfect one that can be successful for the project to use. and explain why it is the best alternative for our design and shows the list components of it. for further information feel free to ask me.
