Problem 1-1|Stress | Mechanics of Materials| Ninth Edition| R.C. Hibbeler|

The shaft is supported by a smooth thrust bearing at B and a journal bearing at C. Determine the resultant internal loadings acting on the cross section at E. SOLUTION: The free-body diagram is shown below. Solve for Cy by taking moment at point B $latex \sum M_B=0&s=1&fg=000000$ $latex C_y\left(8\right)+400\left(4\right)-800\left(12\right)=0&s=1&fg=000000$ Pass a cutting plane at … Continue reading Problem 1-1|Stress | Mechanics of Materials| Ninth Edition| R.C.

Important Concepts in Statics of Rigid Bodies

These points are taken from the book of Russel Hibbeler: Statics is the study of bodies that are at rest or move with constant velocity. A particle has a mass but a size that can be neglected, and a rigid body does not deform under load. A force is considered as a “push” or “pull” of … Continue reading Important Concepts in Statics of Rigid Bodies

What are the important points when dealing with scalars and vectors? I have summarized down below some four important concepts you need to know when solving problems involving scalars and vectors. A scalar can be a negative or positive number. Scalar has magnitude but without direction. A vector is a quantity that has a magnitude, … Continue reading Scalars and Vectors

Geometry Basics

Geometry (from the Ancient Greek: γεωμετρία; geo- "earth", -metron "measurement") is a branch of mathematics concerned with questions of shape, size, relative position of figures, and the properties of space (wikipedia.com). Below are example questions in geometry basics. Take time to answer each of them. Afterward, you can download the answer at the bottom of … Continue reading Geometry Basics
