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

Scalars and Vectors

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
