Please help, I need it now! (data, resolution, response)
1.Calculate the force we need to make to lift a weight of 350N if the force arm measures 30m and the resistance arm measures 7m
2. Calculate the weight I can lift with a force of 3400N, if the d2 is 2.5m and the d1 is 11.2m.
3. Calculate the length of the force arm if I have to lift a weight of 350N with a force of 23N and the resistance arm measures 2.3m.
4. Calculate how much the resistance arm should measure, if we make a force of 2340N to lift a weight of 240N if the force arm measures 12.4dm.
5. Calculate the mass I can lift, if I make a 340N force with a lever 23.4cm of force and 12.4cm of resistance.
