Leokris [45]

When Eleanor Roosevelt says, "There is such a thing as going through the world blindfolded. I have known people who were quite unconscious of the play of the sun and shadow on the hills," she means people can fail to recognize the beauty in the world. This means that these people rarely take advantage of opportunities in life.

The wife of President Franklin D. Roosevelt, Eleanor Roosevelt was the first lady of the United States of America from 1933 to 1945. During this tenure, Roosevelt championed poverty alleviation, access to education and civil rights  as well as travelled to the European and Pacific front lines, when the world was engaged in World War II.

A 100-n weight is hung at the middle of a 4-m long horizontal clothesline. If the middle of the clothesline sags by 1 m, what is
Elena L [17]

The tension on each segment of the clothesline is :  110 N

<u>Given data : </u>

mass of object = 100 n  = 10 kg

Horizontal distance of clothesline = 4 m

middle of clothesline sag s by : 1m

<h3 /><h3>Determine the tension on each segment of clothesline</h3>

<u>First step</u> : calculate the horizontal angle made by the sagging

β = arctan ( 1 m / 2m )  ----- ( 1 )

  = arctan ( 0.5 )

  ≈ 26.57°

Note : Tension in th y axis ( Ty ) = Tsinβ

Therefore :

Tension on each segment can be calculated using the formula below

2Tsinβ - mg = 0

solve for T

T = mg / 2sinβ

  = ( 10 * 9.8 ) / 2 * sin 26.57°

  = 98 / 0.89

  = 110 N

Hence we can conclude that the tension on each segment of the clothesline is : 110 N
