The hammer and scale problem was prevalent on social media platform like Facebook and Instagram few years back.This question is still one of the most challenging physics problem often named as 'physics or strong glue'.In this document, detailed analysis of conditions of equilibrium is carried out using static approach by science of engineering mechanics.The entire thesis is conducted by analyzing free body diagrams of each individual member of setup and then stability curve is plotted in order to visualize stability ranges for the system.Afterwards, equations for getting optimum parameters are derived which are necessary to obtain for attainment of equilibrium of system.Finally the procedure for entire calculation is shown followed by the special case of attaining stability with help of glue is described.Keywords: Center of gravity, center of mass, line of action (L.O.I) of force, normal reaction, seat of normal reaction
