A 40-lb roller, of diameter 8 in., which is to be used on a tile floor, is resting directly on the subflooring as shown. Knowing that the thickness of each tile is 0.3 in., determine the force P required to move the roller onto the tiles if the roller is (a) pushed to the left, (b) pulled to the right.

Day 10Binary Base ten numbers are decimal numbers Binary numbers are base 10 (only 1 and 0, on or off.) every binary has a unique decimal value and vice versa decimal numbers only have digits from 09, and they don’t have to have a decimal in them (ex.33, 493, 39393) example, how to get the decimal number 15 is (1x10^1)+(5x10^0) the value of a binary number and decimal number are different. If you see a number of only ones or zeroes, you have to be told whether it is decimal or binary check the lecture slides for this day Day 11 a breakpoint is a red point that stops to check what is happening the for loop is used when you want the calculations to be performed a certain number of times the first statement is how many times the statement will be executed
