A cast iron beam is a T-section as shown. It is supported and carrying a uniformly distributed load. Which of the following is the correct bending stress distribution diagram if the element is stressed perfectly within plastic limit ? 

In pretensioned system, when prestressed force is transferred by releasing tendon, the end of wire swells and develops wedge effect. At the end, prestressing force becomes zero. This is known as

Which part of the beam is subjected to pure bending in the following figure ?  

Progressive increase in the inelastic deformation of concrete under sustained stress component is known as

Calculate the maximum stress acting on the cross-section of following element :

What are the stresses developed at the top and bottom of a rectangular beam subjected to prestressing force of 50 kN at a distance of 50 mm from bottom. The c/s of beam is 100 x 100 mm

At room temperature the rods are shown in figure. When temperature is raised, what is the nature of stresses developed in each rod, if E_Al < E_s and 

The prestressed concrete is considered as a combination of steel and concrete, with steel taking tensile force passing through the tendon and concrete taking compressive force passing through the C.G. of stress distribution so that the two materials form a resisting couple to resist external moment. This concept is called AS

If AC is principal plane, then magnitude of principal tensile stresses will be 

In a post-tensioning system, high tension steel wires 5 mm to 8 mm diameter about 12 in number are arranged to form a group into a cable with a spiral spring inside. This system is known as

A simply supported beam subjected to uniformly varying load of intensity W at left end (A) reduces to zero at right end (B).Then slope at end B is

If a moment is applied to the hinged end of a prismatic propped cantilever, then the moment at the fixed end will be

A single concentrated load W rolling over the beam of span L will cause the
maximum bending moment and shear force on a section X at a distance x from left support. When the load is on the section, its maximum bending moment will be

Maximum number of unknown forces that can be determined in concurrent force system under equilibrium is

A beam fixed at one end and simply supported at the other end is carrying uniformly distributed load of intensity 'w throughout the span L. Then reaction at simply supported end is

A two span continuous beam having equal spans each of length 1 is subjected to u.d.l. of w per unit run over the whole beam. The beam has constant EI. The bending moment at the middle support is

A beam fixed at one end and free at the other end is subjected to U.D.L. of intensity 'w over the entire span 'L'. Then the deflection at free end will be 

A two span continuous beam having equal spans each of length l is subjected to u.d.l. w per unit length. The beam has constant EI. The reaction at the middle support is

A cable is supported at both ends at the same level and is subjected to U.D.L. over the entire span. If y_C is the central dip and l is the span of a cable, then horizontal thrust developed at the support is

U₁ and U₂ are the strain energies stored in a prismatic bar due to axial tensile forces P₁ and P₂ respectively. The strain energy U stored in the same bar due to combined action of P₁ and P₂ will be
