One thing to note is that the trolley they assembled is made of steel and assembled with machine screws and a funny stud&#x2F;&quot;nut&quot; combination. People&#x27;s experience with your typical dowel&#x2F;screw&#x2F;quarter-turn connector wooden furniture might not have helped them that much.<p>However, because the trolley is pretty light (~14 kg) and its fasteners don&#x27;t require much strength to screw in (vs. the larger screws in wood furniture), it might have mitigated the strength difference between men and women.
