Determine the resultant internal normal and shear force in the member at (a) section a–a and (b) section b–b, each of which passes through point A. The 500-lb load is applied along the centroidal axis of the member. SOLUTION: Part a The free-body diagram of section a-a is shown below.   Solve for normal force at … Continue reading Problem 1-2|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
