The graph shows the potential energy as a function of x-position for a particle in a one dimensional potential energy. The particle is constraint to only move in the +/- x directions. Assume no other forces do work. The kinetic energy of the particle at x = 0 is 0.2 joules. At what points does the particle turn around? See Ch 10.5 for discussion of energy diagrams.

Which one(s) of the following statements is true for limiting positions? Select all that apply.

for 2 can you please do a sketech veriation of it?

are you sure it's not c?, can you show with diagrams

Write the formula for Macaulay Functions?

3) Graphically trace the area which contributes to the load for each joint of the middle parallel chord truss shown on the plan from a distributed area load. Also complete the free body diagram for the section shown for the truss on the bottom figure (with loads) with the appropriate directions (senses). 0.5P (3) 3 P

Find the measurement that is a) most accurate and b) the most precise. 459 ft; 600 ft; 190 ft.

Can someone please help to solve this question following the directions and showing neat work and formulas and drawing all needed diagrams. PLEASE AND THANK YOU!!!
