Can someone post the formula for the percentages of horizontal vs. vertical force of say a ladder leaning on a wall. Like if the ladder weighs 100 lbs and is inclined at 20 degrees off vertical how much of the 100 is pressing straight down and how much is pressing on the wall. I don't know where my old text book is and maybe it's easier to ask here. Guys at the gym like to brag about leg pressing 600 lbs on the sled at 45 degrees and I like to correct them but they don't like to admit it. At 45 degrees wouldn't that be half of the 450 lbs? But I'd like the formula.
