The beam AB has a moment of inertia I = 475 in4 and rests on the smooth supports at its ends. A 0.75-in.-diameter rod CD is welded to the center of the beam and to the fixed support at D. If the temperature of the rod is decreased by 150°F, determine the force developed in the rod. The beam and rod are both made of A-36 steel.

- The steel plate is 0.4m thick and has a density of 7050 kg/m3. Determine the location of its center of mass. And compute the reactions at the pin and roller support.arrow_forwardThe rod has a circular cross section. If it is made of an elastic perfectly plastic material, determine the shape factor for the rod.arrow_forwardA 20-mm-wide block is firmly bonded to rigid plates at its top and bottom. When the force P is applied the block deforms into the shape shown by the dashed line. Determine the magnitude of P. The block’s material has a modulus of rigidity of G = 26 GPa. Assume that the material does not yield and use small-angle analysis.arrow_forward
- The 460-kg uniform beam is subjected to the three external loads shown. Compute the reactions at the support point O. The x-y plane is vertical. Positive values are to the right, up, and counterclockwise. 0 1.2 m Answers: Ox Oy = i Mo= i i A 6.1 KN 1.6 m 19 kN.m B kN kN 1.6 m kN-m 20 C 2.7 KN -1xarrow_forwardThe relay switch consists of a thin metal strip or armature AB that is made of red brass C83400 and is attracted to the solenoid S by a magnetic field. Determine the smallest force F required to attract the armature at C in order that contact is made at the free end B. Also, what should the distance a be for this to occur? The armature is fixed at A and has a moment of inertia of I = 0.18(10-12) m4.arrow_forwardDetermine the slope of the 50-mm-diameter A-36 steel shaft at the journal bearings at A and B. The bearings exert only vertical reactions on the shaft.arrow_forward

Determine the support reactions at A, B, and C. The post at B has a diameter of 40 mm, and themoment of inertia of the beam is I = 875(106) mm4. The post and the beam are made of material having a modulus of elasticity of E = 200 GPa.arrow_forward9arrow_forward
- If the overhanging beam is made of wood having the allowable tensile and compressive stresses of 4Mpa and 5Mpa, determine the maximum concentrated force P that can be applied at the free end. Can you also please explain the calculation of centroid. I'm a bit confused of the values that I need to use. Thank youarrow_forwardThe rigid beam is supported by three 25-mm diameter A-36 steel rods. If the beam supports the force of P=230 kN, determine the force developed in each rod. Consider the steel to be an elastic perfectly plastic material.
