What is the mechanical advantage of a hockey stick that is gripped at point D and hits the puck at point B?

RideAnS [48]

Answer:

Mechanical advantage = Effort distance/Resistance distance

Effort distance = D - Fulcrum = 0.5 m

Resistance distance = A - Fulcrum = 2.0 m

Then,

Mechanical advantage = 0.5/2 = 0.25

Hockey stick is an example of third class where mechanical advantage is less than one as the speed of the end of point A is critical.

The sum of 555 consecutive integers is 270270270. What is the second number in this sequence?

Simora [160]

The second number in the sequence will be 53.

Explanation

The difference between any two consecutive integers is always 1.

Suppose, the five consecutive integers are: $n$ , $n+1$ , $n+2$ , $n+3$ and $n+4$

Given that, their sum is 270. So, the equation will be......

$n+(n+1)+(n+2)+(n+3)+(n+4)=270\\\\ 5n+10=270\\\\5n=270-10=260\\ \\ n=\frac{260}{5}=52$

Thus, the second number in the sequence will be: $n+1= 52+1=53$
