UNIVERSE | SCIENCE | TECHNOLOGY on Instagram: "What looks like brute force is actually smart physics in action. This setup works because of torque, rolling motion, and mechanical advantage. By increasing the effective radius using a wheel the Only required force to move or lift a heavy object drops significantly. Instead of fighting gravity and friction directly, physics redirects the force efficiently. Follow @explaining.science__ for simple explanations of how physics silently powers everyday

How Things Really Work on Instagram: "What makes this bike “unstoppable” isn’t strength or weight — it’s design. Instead of relying on brute-force locks that can be cut or broken, the bike uses a trick that makes stealing it pointless. Key parts either spin freely, detach harmlessly, or lock in a way that prevents the bike from being ridden at all, even if someone manages to grab it. To a thief, it looks like an easy target, but the moment they try to move it, they’re stuck with a useless frame
