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.

Explanation / 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)
