Question

An article suggests that a Poisson process can be used to represent the occurrence of structural loads over time. Suppose the mean time between occurrences of loads is 0.5 year. (a) How many loads can be expected to occur during a 4-year period

Answer 1

Answer:

8 loads can be expected to occur during a 4-year period

Step-by-step explanation:

This question can be solved by a simple rule of three.

Suppose the mean time between occurrences of loads is 0.5 year.

This means that for 0.5 years, 1 occurence is expected.

(a) How many loads can be expected to occur during a 4-year period

0.5 years - 1 occurence

4 years - x occurrences

$0.5x = 4$

$x = \frac{4}{0.5}$

$x = 8$

8 loads can be expected to occur during a 4-year period
