Find Stress of the Rectangular Block

[Future_EngM]

For this question, I need to find the force that will be acting on a rectangular block.

E = 193 x 10^3 MPa
Max. Stress = 210 MPa
F= 2000N

The rectangular block is fixed at both ends (bolted on to another metal object)

I need to find the dimensions for this block. L, length can be as long as 30mm

How do I find the dimensions of the block that will keep the stressunder 210MPa.

I only need the stress that will be there due to the vertical force downwards on the rectangular block.

Help pleaseeeeeeeeee

Is this a school assignment? Is the 2000 N force applied axially to the rectangular block? Or is the 2000 N force a point load applied transversely to the rectangular block midspan?
