- A rectangular steel plate is welded as a cantilever to a vertical column and supports a single concentrated load P. Determine the weld size if shear stress in the same is not to exceed 140 MPaA 1/4 in fillet weld is to transmit a total force of 12,000 lb. If the allowable unit stress in shear on the weld is 15,800 psi, the minimum effective length of the weld must be A. 5.4 B 4.9 in C. 4.3 in D 3.9 in.A bracket is welded to the verical column by means of two fillet welds as shown in the figure. Determine the size of the welds, if the permissible shear stress in the weld is limited by 70N/mm^2.
- (1) What are the methods used to obtain a good weld when welding steel when the carbon content is high? b) Find the appropriate size and length for the weld joint shown in the figure if the strength is equal to (70000Ib) and the allowable shear stress value is 40ksi and the weld rib dimension is (1/4in)appropriate length of the weld joint shown in the figure if the force is equal to (60000lb) and the operating stress value is (60ksi) and the size of the weld is (1/4in).A welded joint, as shown in figure below, is subjected to an eccentric load of 2500 N. Find thesize of the weld, if the maximum shear stress in the weld is not to exceed 50 N/mm2
- Q.2. A bar with a rectangular cross-section is weld as shown. Determine the size weld, if the pemissible shear stress in the weld 80 MPa. The rectangle area of a fillet weld is equal to [ 2t (b+/)]. 31KN Please send the solution within half an hour and thank youA bracket is as shown in figure 2. Determine the uniform weld size for the arrangement. The permissible shear stress of weld material is 80 MPa. Consider the loading condition as shown in figure.A circularbeam, 50 mm in diameter, is welded to support using a fillet weld as in the figure. Determinethe size of the weld, if the permissible shear stress is 100 N/mm2.
- A beam is supported and loaded as shown in the figure. Data: L = 1000 mm, c = 300 mm, f = 100 mm, D = 100 mm, d = 80 mm. The beam consists of different parts that are welded, and the fillet weld size a is 4 mm. The load q is 2 kN/m, and P = 10 kN. Calculate the maximum stress in the welds.a. figure 1 shows a large pressure vessel fabricated by welding together steel plates of 12 mm thickness as shown. If the stress acting normal to the welds must be less than 80 MPa, what is the largest allowable internal pressure? b. determine the state of strain in the tank when the internal pressure is 0.3 MPa. The elastic modulus (?) of the steel is 200 GPa, and the Poisson’s ratio (?) is 0.3. c. The welded joints are to be replaced with equally spaced rivets (loaded in single shear), each with a diameter of 10 mm and maximum allowable stress of 80 MPa. For an internal pressure of 0.3 MPa inside the tank, determine: (i) The minimum rivet spacing (?) along the circumference of the tank. (ii) The minimum rivet spacing (?) along the height of the tank. d. If the pressure vessel is subjected to a temperature change of 50°C determine the change in height. The co-efficient of thermal expansion for steel can be taken as ? = 11.2 × 10−6 °C−1.A steel plate, 80 mm wide and 10 mm thick, is joined toanother steel plate by means of a single transverse anddouble parallel fillet welds, as shown in figure. The strengthof the welded joint should be equal to the strength of theplates to be joined. The permissible tensile and shearstresses for the weld material and the plates are 100 and 70N/mm2 respectively. Find the length of each parallel filletweld. Assume that the tensile force passes through the centre of gravity of three welds.
