Question

Tb = N

Part D: Consider the upward force applied to the beam by the triangular fulcrum. Which of the following is true?

It is equal to the the value of Ta

It is equal to the value of Tb

It is equal to the average value of Ta and Tb

It is equal to the sum of the values of Ta and Tb

Gloria (m 3.00 x 102 kg) got an idea for a Chique-Filet stunt, but things have gone horrible worng, and now she's stuck TB Use this information in the questions below TA = 2.55 m 1.70 m g = 9.81 m/s2 (The bar is made of etherium, which has no mass and is infinitely strong.) CHIKIM Answer the four questions below using three significant digits. (Let g = 9.81 ms.) Part A: What is the Part A: What is the value of the tension in the rope directly holding Gloria? Number Part B: What ist the value of the torque (about the fulcrum) produced by the tension TA? Number TA N·m

Explanation / Answer

As the system is in static equilibrium, All parts of the system will be in equilibrium.

So, Net force on gloria will be zero.

TA= weight of gloria = mass of gloria *g = 300*9.81

TA= 2943 N

B)

Torque,about fulcrum produced by Tension TA is rA*TA = 2.55 * 2943= 7504.65 Nm

C)

Balancing net Torque about Fulcrum,

rA*TA= rB*TB

7504.65 = 1.70* TB

TB= 4414.5 N

D)

Net Upward force on the system must be equal to Net downward Force.

So, Force applied by fulcrum = T_a +T_b

Hence, Option D.
