Kinematics - force analysis 1

[E-N-E ENG]

Please help express F_x on output end in terms of F_y and theta

Thank you

F_y is purely vertical (one degree of freedom along Y-axis)

F_x is purely horizontal (one degree of freedom along X-axis)

Draw a free body diagram. Sum of forces = 0. Draw a force triangle.

One way would be to use a work equation to find the forces, once you've sorted out the geometrical relationship between the x and y locations as a function of theta.

The connecting link is a two force member.
Fx/Fy = tan (theta)

Assuming no friction in the sliding components?

 

[rb1957]

and spherical chickens in a vacuum ... tan (theta) is where I went.

Looks a lot like homework to me
