Answer from: flelea. SHOW ANSWER. c. 62,500 J. Explanation: The ratio of output work to input work expressed as a percent is called as efficiency of the machine. Given : Efficiency = 80 %. Output work or work done by the machine = 50000 J.

Efficiency of a Machinehttps://www.tutorialspoint.com/videotutorials/index.htmLecture By: Mr. Pradeep Kshetrapal, Tutorials Point India Private Limited

Let’s for example say it is wasting 40% material. A machine has a velocity ratio 5 is 80% efficient. What effort would be needed to lift a load of 200 N with the aid of this machine? 27 an electrical motor has efficiency of 80% is needed to power 1000 W machine. what is the required power to be delivered to the motor (1 Point) 800 W 80 W 1250 W 1000 W If your machine or system is capable of making 100 quality products an hour, and it makes only 70, then it is 70% effective, but we do not know how efficient it was, because nothing is said about what we had to put in (how many operators, energy, materials, etc.) to get the 70% effectiveness. Question 2: The mechanical advantage of a machine is 5 and its efficiency is 80%.

A machine has an efficiency of 80

Let's say that x = 20 hours and y = 80 hours. A machine has an efficiency of 25%. Energy is fed into the machine at the rate of 1 kw. The output power of machine is:- In other words, no machine can be more than 100% efficient. Machines cannot multiply energy or work input. To say that a machine has a certain mechanical Introduction to simple machines, mechanical advantage and moments.

The efficiency of a machine is 60%. The machine has a design capacity of 80 units per hour and an effective capacity of 60 units per hour. Find the utilization of the machine. Efficiency = 60% Design Capacity = 80 units per hour

Look back at the pictures of the simple machines and think about which would have the hi Efficiency of a Machinehttps://www.tutorialspoint.com/videotutorials/index.htmLecture By: Mr. Pradeep Kshetrapal, Tutorials Point India Private Limited Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency is at 7.5 hp. A motor ’s efficiency tends to decrease dramatically below about 50% load. However, the range of good efficiency varies with individual motors and tends to A machine uses an effort of 500 N to raise a load of 800 N. it has an efficiency of 80%. Determine its velocity ratio. A machine uses an effort of 500 N to raise a load of 800 N. it has an efficiency of 80%.
