Temperature Change
The beam is fixed at end B and free at end A. It is loaded at end A with the concentrated force 4F. At the same time there is a temperature change ΔT. Calculate the length change Δx. (Modulus of elasticity E, Cross section area A_{S }, Temperature coefficient.)
Calculate angular velocity, angular acceleration
The angular velocity of the circle is defined by the equation ω=3t^{2}+2 rad/sec where t in sec. Determine the magnitudes of the velocity and acceleration of point B on the circle of 1m diameter when t=10 sec.
How to calculate yield strength
The stressstrain diagram for a steel rod is shown and can be described by the equation ε=0.20(1e06)σ+0.20(1e12)σ^{3} where s in kPa. Determine the yield strength assuming a 0.5% offset.
Calculate the Maximum Shear Stress
A steel bar with diameter d = 14 mm is subjected to a tensile load P = 10 kN (see figure). (a) What is the maximum normal stress σ_{max} in the bar? (b) What is the maximum shear stress τ_{max}?
Calculate the Axial Forces of the Truss Members
Torsional MomentStress
Calculate the max stress because of torsional moment on the outer layer of a steel hollow rod when two forces act on it from a distance of 50mm from the center.
Shear bolt connection EC3
Check the shear connection for the IPE450S275 for the design shear V_{Ed}=500KN. Bolts M208.8, plate thickness t=20mm.
