Calculation Example – Rod loading ^{ Featured }
Calculate the internal normal forces at points A,B,C for the rod which is loaded with the forces shown.
Calculation Example – Cantilever Beam with point loads. ^{ Featured }
Calculation Example – Cantilever Beam with uniform loading. ^{ Featured }
Calculate the internal forces for the cantilever beam with the uniform loading q=10KN/m.
Calculation Example – Reinforced Concrete Column at Stress. ^{ Featured }
A rectangular column (400mmX400mm) is constructed of concrete and four steel reinforcing rebars. An axial force of 1000KN is subjected on the column. What is the diameter of the steel bars if the ¼ of the load is transferred to the steel bars and ¾ is transferred to the concrete? ( EST=200GPa, Ec=25GPa)
Calculation Example – Torsional momentStress. ^{ Featured }
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 100mm from the center.
Calculation Example – Calculate tension force using virtual work. ^{ Featured }
Calculate tension force F_AC in cable AC using virtual work for the weight of 10 KN. (The equilibrium is at φ=45 degrees)
Calculation Example – Calculate shear stress for temperature load. ^{ Featured }
A copper bar with a rectangular cross section is held without stress between rigid supports. The temperature of the bar is raised 50°C. Determine the maximum shear stress t. (Assume α= 17.5 x 106/°C and E =120 GPa.)
