ShapeSurf

The app calculates the Geometric Properties of various kinds of plane sections without having to carry a printed book.

You can use this app for:

  • engineering analysis and design
  • stress analysis
  • to calculate the natural frequencies and mode shapes of a machine element
  • students

The app has an intentionally simple interface and the typical sections you would find in a reference book.

As a result the app gives the geometric properties of a bidimensional shape:

 

  • Area: the total area of the shape;
  • Centroid or geometric center: X and Y position; the average arithmetic mean of all the points in the shape
  • Moment of inertia about X and Y axis
  • Inferior and superior section modulus, also called moment of resistance.

 

Most noteworthy the user can export the output with a csv file attachment.

This iOS app is a Cross Section Properties Calculator

The app Calculates the Geometric Properties of Any Plane Figure, giving the x,y coordinates of the vertices.

Furthermore this app helps for the engineering analysis and design, and for stress analysis.

Also the app helps to calculate the natural frequencies and mode shapes of a machine element, and is useful for the students.

As a result you obtain the geometric properties of a bidimensional shape:

  • Area: the total area of the shape;
  • Centroid or geometric center: X and Y position; the average arithmetic mean of all the points in the shape
  • Moment of inertia about X and Y axis
  • Inferior and superior section modulus, also called moment of resistance.
  • Centrifugal moment of inertia, which is the sum of all products between the elementary area dA and the distances between this area and that rectangular system of axis
  • Polar moment of inertia: It measures also the cross section inertia, but the rotation is made around an axis perpendicular to the cross section plane, which intersect the cross section in the centroid geometric center

 

Remember to insert the X,Y coordinates clockwise.
The X axis is horizontal and the Y axis vertical.

Also the user can export data by email.

EXAMPLE
P1 (0, 60), P2 (300, 60), P3 (300, 50), P4 (232.5, 50), P5 (230, 0), P6 (220,0), P7 (217.5, 50), P8 (82.5, 50), P9 (80, 0), P10 (70, 0), P11 (67.5, 50), P12 (0, 50)

Nioshle

This iPhone app is intended for structural engineers, mechanical engineers, detailers, students, and it gives dimensional and structural properties of some European Section.

The output includes:

the moment of inertia, the modulus of section, the radius of gyration for both the principal axes, the weight, the area, and other data.

Also you can select a wide section of profiles:

-IPE, HEA, HEB, HEC, HEM, HL, HD, HP

-UB, UC, UBP, W (metric), HP (ASTM), HG (GOST), H (JIS), W (Imperial), HP (ASTM Imperial)-

IPN, UPE, UPN, U.

In addition the output is in metric or Imperial units, and you can change it in app settings.

Finally you can send results by email.

 Nioshle

Nioshle is an iPhone application developed to provide users of the revised NIOSH lifting equation (1991) .
The app uses a scientifically recognised method.
Therefore the algorithm is based on the Applications Manual of the US Department of Health and Human Services of January 1994 (Thomas R. Waters, Ph.D.,Vern Putz Anderson, Ph.D., Arun Garg, Ph.D).

In addition this iOS app assists the user in the identification of ergonomic solutions to reduce physical stresses associated to manual lifting.
