a crowbar is being used with an actual mechanical advantage of 8. If the input force is 400 Newton’s on the 0.3-meter-long end of the crowbar, what is the output force on the short end?
A) 120 N
B) 960 N
C) 50 N
D) 3200 N
Well, let me see... Ah, the crowbar! Quite the tool, isn't it? Now, for this particular situation, we're dealing with some mechanical advantage calculations. In this case, we have an actual mechanical advantage of 8, and an input force of 400 Newtons on the 0.3-meter-long end of the crowbar. So, to find the output force on the short end, we can use the formula:
Output force = Input force × Actual mechanical advantage
So, let's plug in the numbers:
Output force = 400 N × 8 = 3200 N
Voila! The output force on the short end of the crowbar is 3200 Newtons. So the answer is D) 3200 N.
nvm I put d
To find the output force on the short end of the crowbar, we can use the formula for mechanical advantage:
Mechanical Advantage = Output Force / Input Force
Given that the mechanical advantage is 8 and the input force is 400 Newtons, we can rearrange the formula to solve for the output force:
Output Force = Mechanical Advantage * Input Force
Output Force = 8 * 400 Newtons
Output Force = 3200 Newtons
Therefore, the output force on the short end of the crowbar is 3200 Newtons.
The correct answer is D) 3200 N.
To find the output force on the short end of the crowbar, we can use the formula for mechanical advantage:
Mechanical Advantage (MA) = Output Force / Input Force
Since the actual mechanical advantage of the crowbar is given as 8, we can substitute this value into the formula:
8 = Output Force / 400
To find the output force, we can rearrange the formula:
Output Force = MA * Input Force
Substituting the given values:
Output Force = 8 * 400
Output Force = 3200 N
Therefore, the correct answer is D) 3200 N.
