Problem 1-2|Stress | Mechanics of Materials| Ninth Edition| R.C. Hibbeler|

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|

Two solid cylindrical rods (1) and (2) are joined together at flange B and loaded, as shown in Figure P1.3/4. The diameter of rod (1) is 1.75 in. and the diameter of rod (2) is 2.50 in. Determine the normal stresses in rods (1) and (2). SOLUTION: Cut a FBD through rod (1). The FBD … Continue reading Mechanics of Materials by Timothy A. Philpot, P1.4

A stainless steel tube with an outside diameter of 60 mm and a wall thickness of 5 mm is used as a compression member. If the axial normal stress in the member must be limited to 200 MPa, determine the maximum load P that the member can support.

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
