Step 1
The formula for normal stress is: Normal stress = Force / Area Given that the force P is 16 kN and the cross-sectional area of cable BD is 68 mm^2, we need to convert the force to Newtons and the area to square meters: Force = 16 kN = 16,000 N Area = 68 mm^2 = Show more…

A 2.5 cm diameter bolt is in double shear and carries a load of 30 KN. What is the shear stress in the bolt
Anand J.
Calculate the shear stress points indicated on the compound. The shear force at the specific cross section of the beam is 500 kN. Draw a neat sketch to show the shear stress distribution across the cross section. 300 mm 150 mm 30 mm B Trapezoidal with linear slope 290 mm D 30 mm E 200 mm Calculations: ar{y} = mm (from the top of the section)
Adi S.
A bolt thread is designated as M 20 x 1.5 with core diameter equal to 18.16 mm. If 20 kN tensile load is applied, calculate the shear stress across the thread considering that there are already 8 threads engaged with the nut. a. 29.21 MPa b. 45.33 MPa c. 26.53 MPa d. 7.96 MPa
