The largest average shear stress must occur where the tube’s thickness is the smallest. / Die grootste gemiddelde skuifspanning moet plaasvind waar die buis se dikte die kleinste is.

The shear flow measures the force per unit length along the cross section. / Die skuifvloei meet die krag per lengte-eenheid langs die dwarssnit.

None are false. / Geeneen is vals nie.

The product of the average shear stress and the thickness of the tube is the same at each location on the cross section. This product q is called shear flow. / Die produk van die gemiddelde skuifspanning en die dikte van die buis is dieselfde by elke plek op die dwarssnit. Hierdie produk q word skuifvloei genoem.
