Load transmission/action • The transmission of load through a structure can be complex but in any particular case – The applied load can usually be classified into 4 types • Axial • Shear • Bending • Torsion – The individual members of the structure can be examined as to their ability to carry the share of the loads Load transmission/action

Long trusses are often used to construct large cranes and electrical transmission towers. The method of joints requires that many joints be analyzed before we can determine the forces in the middle of a large truss. So another method to determine those forces would be helpful.

Solids and Structures 1 (ENGG110) 2023 Equilibrium of a rigid body Objectives • To demonstrate how 2-D equations of equilibrium apply to a rigid-body (in which not all forces converge at a point) • To practice drawing free-body diagrams • To identify two-force members We can use ‘equilibrium at a point’ to determine the cable forces Fx=0; Fy=0 But we need to use ‘equilibrium of a rigid body’ to determine t...

Solids and Structures 1 (ENGG110) 2023 Frictional Forces Draw FBD of block at rest on inclined surface Pause the video and try this! FBD of block • W is weight of block = Mg due to gravity acting through G centre of mass • N is normal reaction between block and surface • F is frictional force opposing motion What is friction? Max friction Min friction

Solids and Structures 1 (ENGG110) 2023 1-Pin-jointed Frames SIMPLE TRUSSES, THE METHOD OF JOINTS, & ZERO-FORCE MEMBERS Today’s Objectives: You will be able to: a) Define a simple truss. b) Determine the forces in members of a simple truss. c) Identify zero-force members in a simple truss. APPLICATIONS Trusses are commonly used to support roofs. For a given truss geometry and load, how can you determine the forces in the truss members and thus be...

Solids and Structures 1 (ENGG110) Equilibrium of a particle (at a point) Outline • Co-planar (2-D) equilibrium of forces • FBDs • Concept quiz • Support reactions in 2-D • Quick summary Hook TYPICAL APPLICATION In crane lifting operations, the forces in the wires and chains that hold up the load have to be calculated to determine if they are strong enough and in the right position to stabilize the load. In this application the forc...
