A solid cylindrical steel (G=11x10^6 psi) shaft AB, has two different diameters and is secured at both supports A and B. Such that no rotation at the supports can occur. A roque of 976 in lbs applied at junction C as shown. Calculate the reaction at A:

please list the reactions at A from the options below

A floating column AB of length L, is modelled with top end fixed and bottom end yielding under column load. The yielding support can be visualised as an axial spring of stiffness k. If an axial force Pis applied at a distance 'a' from the top, determine reactions at the ends A and B and displacement at the end B.

A Pin spanner as shown in Figure, requires moment of 80 Nm to turn the 200 mm diameter shaft about its center O under the action of the applied force P. determine the contact reaction force on the smooth surface at the point A. Engagement of the pin at B may be considered to occur at the periphery of the collar OPTIONS:(MULTI CORRECT(MAY BE)): 1.Reaction at Point A is around 1047 N 2.Value of force P is around 102 N 3.Value of force P is around 133 N 4.Reaction at Point A is around 720 N 5.Reaction at Point A is around 1321 N 6.Value of force P is around 200 N 7.Value of force P is around 213 N 8.Reaction at Point A is around 970 N
