A beam of uniform cross section whose flexural rigidity EI = 2.8 × 1011 N·mm2, is placed on three supports as shown. Support B is at small gap Δ so that the moment at B is zero.
1. Calculate the reaction at A.
2. What is the reaction at B?
3. Find the value of Δ.
Compute the value of EIδ at the overhanging end of the beam in Figure P-870 if it is known that the wall moment is +1.1 kN·m.
Find the value of EIδ at the center of the first span of the continuous beam in Figure P-869 if it is known that M2 = -980 lb·ft and M3 = -1082 lb·ft.
Determine the values of EIδ at midspan and at the ends of the beam loaded as shown in Figure P-868.
Determine the value of EIδ at the end of the overhang and midway between the supports for the beam shown in Fig. P-860.
Determine the value of EIδ under P in Fig. P-859. What is the result if P is replaced by a clockwise couple M?
In Fig. P-696, determine the value of P for which the deflection under P will be zero.
Determine the value of EIδ at the left end of the overhanging beam in Fig. P-693.
The beam shown in Fig. P-689 has a rectangular cross section 4 inches wide by 8 inches deep. Compute the value of P that will limit the midspan deflection to 0.5 inch. Use E = 1.5 × 106 psi.
Determine the midspan value of EIδ at the left end of the beam shown in Fig. P-688.
