What is the value of tension 𝑇1 𝑎𝑛𝑑 𝑇2 in the figure shown above 👆🏾👆🏾👆🏾?

1. T1 = 14.33KN and T2 = 17.8KN
2. T1 = 28.87 KN and T2 = 14.33KN
3. T1 = 14.33KN and T2 = 28.87 KN
4. T1 = 17.87 KN and T2 = 28.87 KN

It’s preferable if you show us the solution on the discussion group @cotmp

📌Basic terms for Mechanics

🚧1. Torque or Turning Force

➡️It is the total amount of force which is required to create acceleration on moving substance.

🚧2. Couple

➡️Two forces those acts on equally, parallely & oppositely on two separate points of same material.

🚧3. Moment

➡️It is the amount of moving effect which is gained for action of turning force.

🚧4. Stress

➡️It is the force that can prevent equal & opposite force.

➡️That means, it is the preventing force.

➡️If one force acts on outside of a material, then a reactive force automatically acts to protest that force.

➡️The amount of reactive force per unit area is called stress.

➡️For instance:- Tensile Stress, Compressive Stress, Thermal Stress.

🚧5. Strain

➡️If a force acts on a substance, then in that case if the substance would deform.

➡️Then the amount of deformation per unit length of that substance is called strain.

🚧6. Spring

➡️It is one type of device which is being distorted under certain amount of load & also can also go to its original face after the removal of that load.
Its function

⏺i. To store energy

⏺ii. To absorb energy

⏺iii. To control motion of two elements

🚧7. Stiffness

➡️Load per unit deflection. The amount of load required to resist the deflection.

🚧8. Specific Weight

➡️Weight per unit volume of the fluid.

🚧9. Specific Volume

➡️Volume per unit mass of the fluid.

🚧10. Specific Gravity

➡️It is the ratio of specific weight of required substance to specific weight of pure water at 4 degree centigrade temperature.

👉እስቲ ስለ Shear Force Diagram እና Bending Moment Diagram አጠር ያለ ማብራርያ ልስጣቹ ...

🚧Shear Force Diagram = የአንድን አካል ርዝመት ‘ X ’ ብንለው በፎርሶች የሚፈጠረውን ሺር ፎርስ ደግሞ ‘ Y ’ ብንለውና ግራፍ ላይ ስለን እያንዳንዱ የርዝመቱ ነጥብ ላይ ያሉትን ሺር ፎርሶች በመስመር ስናገንኛቸው የምናገኘው ቅርፅ ነው SFD

🚧Bending Moment Diagram = ከ SFD ጋር አንድ ሆኖ ነገር ግን ለ Moment ሲሆን Bending Moment Diagram (BMD) ይባላል

🚧Concentrated Load ሲኖር SFD ቀጥ ብሎ ወደጎን ይሄዳል ወይም በሌላ አገላለጽ Constant ይሆናል BMD ደግሞ linearly ወይም right angle triangle በሚመስል መልኩ ይሄዳል::

🚧Distributed Load ሲኖር SFD linear ይሆናል BMD ደግሞ Parabolic ይሆናል::

⭐️ሁልጊዜ BMD ከ SFD በ አንድ ዲግሪ ይበልጣል ( SFD constant ሲሆን BMD linear እንዲሁም SFD linear ሲሆን ደግሞ BMD parabolic ይሆናል)

🏷Maximum Bending Moment = SFD ከፖዘቲቭ ወደ ኔጌቲቭ የሚቀየርበት ነጥብ ላይ ነው Moment Maximum የሚሆነው።

🏷Minimum Bending Moment = SFD ከኔጌቲቭ ወደ ፖዘቲቭ የሚቀየርበት ነጥብ ላይ ይገኛል፡፡
