If the temperature of the bar is raised from 25°C to 75°C, find the stresses induced in each rod by assuming (a) if the supports do not yield and (b) if the supports yield by 0.25 mm. Take E1= 200 kN/mm2, E2 = 30 kN/mm2, E3 = 100 kN/mm2, And, a1= 1.2 x 10-5/°C, a2= 1.8 x 10-5/°C d3= 1.6 x 10-5/°C Q3/ * 0= 150 mm 0= 100 mm 0= 50 mm Figure 2 200 mm 300 mm 500 mm (1) 01= 194.78 N/mm2, a2= 48.7 N/mm2, 03= 21.64 N/mm2/(2) 01= 133.14 N/mm2, 02 33.28 N/mm2, a3= 14.79 N/mm2 (1) 01- 184 3anm2, 92- 44.73 N/mm2. 03- 24.64 N/min2/ (2) a1 143.14 N/mm2 o2 36 21 N/mm2, 03-14.79 N/mm2 (1) a1- 190.28 N/mm2, 02 48.26 N/mm2,
A rectangular polypropylene [E = 6.200 MPa] bar (1) is connected to a rectangular nylon [E = 1,400 MPa] bar (2) at flange B. The assembly (shown in the figure) is connected to rigid supports at A and C. Bar (1) has a cross-sectional area of A₁ = 920 mm² and a length of L₁ = 1220 mm. Bar (2) has a cross-sectional area of A₂ = 2630 mm² and a length of L₂ = 570 mm. After two loads of P = 3.8 kN are applied to flange B, determine: (a) the forces in bars (1) and (2). (b) the deflection of flange B. (a) F₁ = F₂ = (b) UB = i i i A kN KN mm L₁ (1) P B L₂ (2)
I need help on this question:
Question 1: [Strain Energy Due to Direct Stresses] A steel bar of a length, diameter and Young's modulus of 400 mm, 20 mm and 200 GPa is placed concentrically within a brass tube which has an outside diameter, thickness, length and Young's modulus of 30 mm, 4 mm, 400 mm long and 100 GPa respectively. The compound bar hangs vertically with its upper end rigidly fixed with a collar fitted to the bottom end. The application of a load P re sults in the compound bar storing a total of 7J of energy. Calculate: 1.1 The gradually applied load 1.2. The suddenly applied load
Rigid bar ABCD is loaded and supported. Bars (1) and (2) are unstressed before the load P is applied. Bar (1) is made of bronze [E= 100 GPa] and has a cross-sectional area of 400 mm2. Bar (2) is made of aluminum [E= 70 GPa] and has a cross-sectional area of 600 mm2. After the load P is applied, the force in bar (1) is found to be 60 kN (in compression). Determine: (a) the stresses in bars (1) and (2).(b) the vertical deflection of point A.(c) the load P.
