Hooke’s Law

A. Perfect Elastic
1) Elasticity is a material property that causes it to restore to its original shape after distortion. If it restores itself to exactly the original configuration, the system is then considered to be Perfectly Elastic. Every material has its own level of elasticity with some like the piano wire or marbles having higher elasticity than chewing gum or clay dough.
A perfectly elastic material wouldn’t continue to function under these circumstances if loads applied to the system surpasses the elastic limit. When this occurs, the system starts to plastically deform (structure wouldn’t return to its original shape).











2) Materials elasticity is defined by a proportionality known as the Modulus of Elasticity. This is the ratio of rate of strain in relation to stress. A material with a higher modulus would be able to handle forces better than a material with a lower modulus. It also means that a material that has a higher modulus of elasticity has the ability to take more stresses without permanent damage (contains more elastic properties).



E = Modulus of Elasticity















3) Compressive strain is the ratio of decomposition caused by compressive load per unit length measured along the longitudal axis. It is measured when the length of a structure changes because of a compressive force.







B) Torque 1)











NB. Specifications from (http://www.mdisensor.com/products/product_detail)

Torque sensing products have a wide range of application in many industries; from Agriculture where sensing equipment is needed in harvesters to the Aviation industry where it is needed in helicopter engines. They come in a wide variety of sizes and applications; from hand tools to onboard sensing equipment. There is a need for these products to be:
• Robust; it should be able to handle difficult conditions such as dirt, grit, grease etc.
• It should be easy to...
