Calculating Deflections on a Curved Beam

[Mechaman]

Homework Statement

Working out deflections on a semi circular bar.

Homework Equations

3WR^3π / 2EI

Where E = 200GN/m^2
W = 9.81N
R = 150mm
I = 5.625 * 10^-3 (bar is 25mm * 3mm)

The Attempt at a Solution

(3)(9.81)(0.15)^3π / (2)(200*10^3)(5.625 * 10^-3) = 13868.56

I have data that says it should be more like
1.3870359

I'm not exactly sure of the units either?

Heck, we're not even sure what the problem is.

Is there a figure or some other description of what you are trying to solve? Is this bar laterally loaded? Is it a point load? Distributed load? Are the ends both fixed?

The semi circle bar is fixed at one point and has a point load at the other end.

Maybe you can insert a picture?
