Load on Structures

Civil engineers primarily deal with beams in their day-to-day applications. A beam is a structural member that resists shear loadings. There are various types of beams such as cantilever beam, simply supported beam, and over the hanging beam. All these beams have a different end and loading conditions.

3. A rigid bar is supported by two rods which are made of different materials. Rod A is a steel
rod which has a modulus of elasticity of 29 000 ksi and Rod B is made of bronze which has a
modulus of elasticity of 14 500 ksi. If the bar is horizontal before applying the load P, find the
distance x that locates the position where P must applied so that the bar will remain horizontal.
