Please solve this problem THank you Two slabs sandwich a square plate heater of dimensions 30 cm by 30cm. One slab is 13 mm thick (k =0.67 W/m°C) while theother is 36 mm (k = 0.47 W/m°C). If the outside temperature of both slabs is 60°C, calculate the maximum temperature in thesystem. The rating of the heater is 2 kW. Write your answer to two decimal places.!!!3!

Given data: t1=13 mmk1=0.67 W/m°Ct2=36 mmk2=0.47 W/m°CTO=60°CQ=2 kW Need to determine the maximum…

Joe takes his little brother Andy down the the playground for an afternoon out. Andy would like to ride the seesaw, but the difference in their sizes, Joe weights 160lbs and Andy weighs 641lbs, makes this difficult. Joe sees a solution from his engineering class and moves the fulcrum from the middle to a new place. The seesaw is 3.5m long. After Joe moved the fulcrum how long was the seesaw on Joe's side?
1) Prof. K. climbed a wall and is now stuck and hungry. One of her ME 242 students saw this opportunity to test one of their pulley mechanisms to lift some pizza boxes for Prof. K. If the student is pulling the free end with a velocity of 2.75 ft/s. a) What is the mechanical advantage between the student and the pizza boxes? Hint: The link between pulleys 1 and 4 is rigid (meaning that they must move together. This is the key to solving this problem! b) What is the velocity of the pizza boxes? Be sure to indicate which direction it is moving. [Ans. to check: 1.375 ft/s] PizzA 49°F Sunny O 4x 99+ P Type here to search End PgUp PgDn PrtScn Home
The pulley below has a mechanical advantage of 3 and has a load of 300N assume an ideal pulley without friction losses, determine the following: a) what input force (input) do you apply to lift the load of 300 N? B) what is the tension in the 3 lines of the ropes of the pulley on the output side with the load as illustrated in the diagram? C) if the load is lifted to a height of 12 cm, how much rope is pulled on the input side d (in) in the diagram? D) how much work in joules (j) is required to lift the 300 N load 12 cm (0.12m)? E) how much power in watts (w) is required to lift the 300N load a distance of 0.12m in 20 seconds.
