L लंबाई (span) वाले एक सरल समर्थित धरन (simply supported beam) के केंद्र पर एक संकेंद्रित बिंदु भार (isolated point load) W लगा है। यदि इसकी नमन दृढ़ता (flexural rigidity) EI है, तो इसका अधिकतम विक्षेपण (maximum deflection) कितना होगा?

When a bar of length l and uniform cross-section is rigidly fixed at the upper end and hangs freely, the total elongation produced in the bar due to its own weight is given by (where w = weight per unit volume and E = Modulus of Elasticity):

The hoop stress set up in a thin cylinder subjected to internal fluid pressure is:
