Three forces are applied to an object, as shown in the diagram below. f1 = 30 n, f2 = 34 n, f3 = 20 n, d1 = 25 mm, d2 = 20 mm, d3 = 10 mm, θ3 = 500. what is the resultant torque around the point 'x', in units of nm?

Apulley system is used to lift a 2,000 newton engine up a distance of 3 meters. the operator must apply a force of 250 newtons to the chain of the pulley system to lift the motor. to lift the engine 3 meters, the operator must pull a total of 30 meters of chain through the pulley system. what is the value of di?

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?
