Codes require engineers to calculate the deflection to live load, to do this you must first calculate the deflection due to dead and live, and the deflection due to dead load seperately, why can deflection due to live

Determine (a) the x, y, and z components of the 900 N force, (b) the angles  θx,  θy, and  θz that the force forms with the coordinate axes.    Note: Please show the complete solution for the problem together with the free body diagram in resolving the force into its components. As it is needed for my review. Thank You!

I WOULD LIKE TO KNOW HOW TO SOLVE THESE TWO QUESTIONS IN THE IMAGE ATTACHED

you are analyzing the maximum deflection of a beam fixed at one end and loaded at the other end. The length is varied by a factor of 1.49 by what factor does the max deflection vary to keep all other parameters constant

please base your answer on the given choices thank you 1.142mm 0.742mm 0.542mm 0.342mm

TORSION The UNITS OF FINAL ANSWERS are indicated in the questions, thua no need to encode units. However please provide the UNITS ANALYSIS, USE OF CORRECT CONVERSION RATIOS in your hand-written solution. INCOMPLETE/NO SOLUTION means NO CREDIT. Please DO NOT USE SCIENTIFIC NOTATION in your final answera. A steel shaft with a diameter 51 mm and length 1.40m transmits 63.50 kW from an electric motor to a compressor.The allowable shear stress is 58.75 MPa and the allowable angle of twist is 2.2degrees. G-83 x 10^3 psi Determine the polar moment of inertia (in mm 4) of the steel shaft. Please DO NOT USE SCIENTIFIC NOTATION in your fina answers Please wrice Tinal answers ro 2 decimal places.) 664172.0551 mm4
