A tool has two holes and has them fixed. The force is applied at the tip of the tool.
The deformation, the displacement distribution, and the stress distribution are solved.
Unless specified in the list below, the default conditions will be applied.
Results will vary depending on Femtet version and the PC environment.

The material is iron.
The inner faces of the holes are fixed by boundary condition.
The force is applied on the top face of the tool by the distributed face load boundary condition.

The value of distributed face load is set assuming that a total of 100 kg is applied to the tip face of the tool.
The area of the tip face: 0.0052x3.14=0.0000785 m2
Total load: 100×9.8 = 980 N
Distributed load: total load/area of front face: approx.12484076 N/m2 (= Pa )

The Z-direction displacement is shown below by contour. The contour diagram shows the magnitude of displacement.
The displacement in the -Z direction is larger towards the tip of the tool.
The vectors of the stress are shown below. The unit is [Pa].
The upper part of the tool is getting the tensile stress, whereas the lower part is getting the compressive stress.
