A polymer bat is resting on two supports and a load of 500 N

A polymer bat is resting on two supports and a load of 500 N is applied midway between the supports (as illustrated).The bar is manufactured from polyvinyl chloride and is 2 cm wide by 0.5 long. Under application of the load the maximum permissible (reversible) deflection is 0.5 mm AND the bar must not undergo any permanent deformation. What is the maximum span (separation distance between supports) that the bar can bridge (report in cm)? What is the limiting mechanical property?

Solution

l=10.66cm
