9. A pivoted double block brake as shown in figure below has two shoes that subtend an angle of (20) 100°. The diameter of the brake drum is 500 mm and width of the friction lining is 100 mm. The coefficient of friction is 0.2 and the maximum intensity of pressure between lining and brake drum is 0.5 N/mm?. The pivot of each shoe is located in such a manner that the moment of the frictional force on the shoe is zero. Calculate the torque capacity of each shoe. Page 3 of 5 Drum Pivoted Shoes

1. Energy consumption in a country from 2001 to 2011 increased from 1041.3 million to 1526.1 million BOE (barrels of oil equivalent). If the high calorific value (HHV) of the oil is 141,000 kJ/gallon what is the increase in energy consumption over 10 years in Joule units. What is the rate of energy consumption per year? 2. Based on data on the rate of energy consumption per year from question no. 1, if the growth rate energy 2.5% per year, calculate the doubling time (td) and what is the approximate rate of energy growth in 2021.

What is the magnitude of the roller reaction in lb? (2 decimals)

Topic: Dynamics (Work, Energy, Power) Determine:  (a) The force (parallel the inclined) required to move the block. (b) The rate of work done in 10 seconds (c) The initial velocity (Vi) of the block if its velocity at 10 meters is 30 m/s. *Please answer with complete and in order solution. *Three decimal places all final answers. *Include figures and Free Body Diagram with proper labels. *Enclose with a box all final answers.   THANK YOU

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).

Which of the following is FALSE regarding the continuum assumption of fluids? Select one: a. Uncertainties within the molecular properties of the fluid will be neglected b. Limit concepts can be applied on fluids c. Fluids with same composition may have different properties d. The fluid will be analyzed in the macroscopic level Which of the following does NOT describe a difference between liquids and gases? Select one: a. Liquids form a free surface while gases do not b. Liquids have lower bulk modulus of elasticity than gases  c. Specific gravities of liquids are higher than gases d. Viscosity of liquids decreases as temperature increases while on gases, viscosity increases with temperature

(Thermodynamics) Plz solve the question and show the steps

Please show all your work no ai. I'm trying to truly understand.

can you please provide the solution for the answer in Reaction Ay?
