From experience everybody knows if you put your arm out of car window at high speed(150km/h), it's a lot easier to hold arm angled backward then hold arm straight out(prependicular to airlfow).So conclusion will be that drag force is reduced..

Can wing sweep in same manner reduce total drag force at speeds up to 250km/h?

Pulling angled "beam" with rope in water will be easier than if "beam" is prependicular to flow.Right beam has smaller lift force but also less total drag force.Is this correct?
