Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

The University of Oklahoma School of Civil Engineering and Environmental Science spring 2024 Semester Problem 3 (30 pts.) ENGR 2411 Applied Engineering Statics Prerequisite Quiz Page 4 of a Your friend Dave loves hanging on the OU banner poles attached to the light poles on campus, this is despite your strong disapproval of their behavior. As an engineering student you are super concerned about the moment acting at the base of the light pole. What if Dave breaks the light pole! Calculate the moment acting about the base of the light pole (point O) when Dave is angled 45° from the horizontal banner pole. Dave weighs 120 lbs. Assume the force exerted by Dave on the banner pole is aligned with their arm that is holding onto the pole (ie. at 45°). B 15ft tf8 Disclaimer: Dave is fictional and does not represent any actual person.

I only need help with answering part F please!
An electric hot water heater consumes 3.1 kilowatts of electricity and converts it to heat. How long will it take the water heater to heat a 67 gallon tank of water from 10 degrees Celsius to 50 degrees Celsius? (1 kilogram of water is 0.37 gallons, 1 Calorie = 4200 J). It may be helpful to refer back to the weekly handout for guidance on this problem. Your final answer should be in minutes (rounded to the nearest 10 minutes).
