Teacher Tech BriefTensile Strength Test StrandContextThe different materials used in constructing theSpace Shuttle EMU were chosen because they eachfeatured properties deemed desirable for spacewalkin g. Depending upon their intended purp o s e,material may have to withstand tears, punctures,temperature extremes, bending, abrasion, or anycombination of the above.PurposeThis test stand measures materials for their resistanceto tensile (stretching) forces.PrincipleUsing the mech a n i cal advantage of a pull ey setup, t e n-sile forces are exe rted on test samples until they bre a k .Materials and Tools ChecklistWooden base (6" x 1" x 4')Threaded iron pipe (1 pc 3/4" x 2')(2 pcs 3/4" x 3')Pipe elbows (2 pcs )Pipe flanges (2 pcs )Screws for flangesPulley (1 single)Pulley block (1 double, 1 triple)Cord for pulleysClamps (2 )Metric RulerPointer (stiff wire)Hose clamps (2 pcs )Lead weights (25 kg)BucketScrewdriverPipe wrenchMaterials to be testedEye ProtectionOperationObtain diffe rent fabric samples from re m n a n ttables at fabric stores.
