Question 1: A crane is used to carry a load of 10 kN as shown in Figure 1. The weight of the beam in the crane is assumed to be 200 kg. When the load is in the middle span of the beam, please define: a) Maximum moment developed in the beam. b) Maximum bending stress due to the external loading on the beam. 100 mm 112 mm 12 mm 150 mm 30° 2 m 12 mm 157 ) kN 3 m . 1 m Beam cross section

Dependence on mechanical properties

The mechanical properties of materials are those structures that include the reaction to the load used. Metal switching features determine the scope of the usefulness of the content and establish the expected service life. Machine structures are also used to help distinguish and identify material objects. The most common mechanical properties considered are strength, ductility, stiffness, impact resistance, and resilience to fractures.
