407 Six simple Machines Problems Part 2:
12pts) SECTION 1: FORCE MOVED, For each machine problem below:
- Lever that is 2.13 meter on one side and 7.33 meters on the other. If it functions at 75.1% efficiency, what is the maximum weight that can be lifted using 435N of force?
- An incline plane that is 2.45 meters high and 5.67 meters long. If it functions at 68.4% efficiency, what is the maximum weight that can be lifted using 723N of force?
- A 10.1cm radius wheel fixed to a 3.14cm radius. If it functions at 57.8% efficiency, what is the maximum weight that can be lifted using 471N of force?
- If the wedge is 12.3cm long and 2.33cm at the base. If it functions at 94.2% efficiency, what is the maximum separation force using 159N of force?
- A pulley with a ideal mechanical advantage of 4.00. If it functions at 77.4% efficiency, what is the maximum weight that can be lifted using 139N of force?
- A tire jack with a screw pitch of 0.051m and a 3.68m long handle. If it functions at 5.20% efficiency, what is the maximum weight that can be lifted using 14.6N of force?
12pts) SECTION 2: FORCE APPLIED, For each machine problem below:
- Lever that is 2.13 meter on one side and 9.23 meters on the other. If it functions at 57.8% efficiency, what applied force is necessary to lift 55.6N?
- An incline plane that is 2.45 meters high and 8.23 meters long. If it functions at 81.2% efficiency, what applied force is necessary to lift 94.1N?
- A 10.0cm radius wheel fixed to a 2.33cm radius. If it functions at 88.0% efficiency, what applied force is necessary to lift 50.0N?
- If the wedge is 5.67cm long and 1.11cm at the base. If it functions at 96.0% efficiency, what force is needed to produce 62.3N of separation?
- A pulley with a ideal mechanical advantage of 2.00. If it functions at 83.3% efficiency, what applied force is necessary to lift 39.3N?
- A tire jack with a screw pitch of 0.051m and a 2.63m long handle. If it functions at 8.20% efficiency, what applied force is necessary to lift 1329N?
