F Standand Exerclse Leaning Ladder And the magnitude of Torque can be calculated from: IT-HEsin? In the questions below, aszume all torques are calculated about the CENTER OF THE BEAM (marked with a red dot). Given a beam with mass M and length L = 4.2 m attached to wall by a hinge at one end and a horizontal wire (with tension FT1) attached to the other end of the beam. A mass m is attached to the beam a distance d 2.9 m from the left edge of the beam by massles wire (with tension F. The beam make: angles with the wall and wire shown where 8 33 and e 57 IE Disk and String Interactiv Exampio E Sphere Incline T1 Standard Exercise Gymnast (w/ Work) Stanard Exercise Hanging Beam 2 T2 Tipiser9 12.9.00 Optional Evercise Tipler6 12.P.010 - Optional Standard Exercise Tipler6 12.P.012. Optional Tipler6 12.P.018 Optional 1) when calculating the torque due to FTI on the beam labout the center of the beam) -r Flsin9, is: F1-2.1 m 0.8 m F 4.2 m 2.9 m ?? 7:56 2018-04-027 43Explanation / Answer
1)
r is distance to the point of application of force.
So,
r=4.2/2
=2.1m
2)
It will be 330, angle between r and F vector.
3)
It will be out of the page, as we know direction is r*F
4)
It will be
2.9-2.1
=0.8m
5)
The angle will be 570
6)
the direction will be into the page (clockwise)
