Why is a sit up a second class lever?
Why is a sit up a second class lever? Second-Class Levers In a second-class lever, the resistance lies between the fulcrum and the force, as in a wheelbarrow. Exercises that require plantarflexing the ankle, such as seated or standing calf raises, employ a second-class lever. What’s an example of a second class lever? In a […]
Does frequency change power?
Does frequency change power? Frequency of the system will vary as load and generation change. Increasing the mechanical input power to a synchronous generator will not greatly affect the system frequency but will produce more electric power from that unit. Can I use a 60 Hz device in a 50 Hz power frequency? Electrical machines […]
