It is more than 90 years old. An American Elm Tree in the heart of downtown Oklahoma City, it survived the bomb’s blast and witnessed one of the worst terrorist attacks on American soil. Today, we call it the Survivor Tree.
Before the bombing, the tree was important because it provided the only shade in the downtown parking lot. People would arrive early to work just to be able to park under the shade of the tree’s branches.
On April 19, 1995, the tree was almost chopped down to recover pieces of evidences that hung from its branches due to the force of the 4,000 pound bomb that killed 168 and injured hundreds just yards away. Evidence was retrieved from the branches and the trunk of the tree.
When hundreds of community citizens, family members of those who were killed, survivors and rescue workers came together to write the Memorial Mission Statement, one of its resolutions dictated that “one of the components of the Memorial must be the Survivor Tree located on the south half of the Journal Record Building block.”
Answer:
plz mark me as brainlst
Explanation:
The expression of the weight of the bar is given by,
W=mg
Here, g is the acceleration due to gravity
Substitute all the values
W=(18kg)(9.81m/s2)=176.58N
The expression of the angle θ
by using free body diagram is given by,
tanθ=ACBO+OC
Substitute all the values
tanθ=(1.3m)(1.2m)+(0.75m)θ=tan−1(1.31.95)θ=33.69∘
Take moment about point O and obtain the value of tension T.
∑MO=0Tsinθ×AC+W×(AO2cosθ1)−Tcosθ×CO=0
Substitute all the values
Tsin(33.69∘)×(0.75m)+(176.58N)×(1.5m2cos60∘)−Tcos(33.69∘)×(1.3m)=0T×0.416m+66.22N⋅m−T×1.081m=0−T×0.665m+66.22N⋅m=0T=−66.22N⋅m−0.665mT=99.58N
I would say the second answer
