You can throw all the objects in it and roll it around instead of holding the objects and they fall out of your hands/arms (if too much).
Answer:
F = - K X force constant for spring
a = F / m maximum acceleration
F = 4.5 kg * 26 m/s^2 = 117 Newtons
(A) K = 117 N / .038 m = 3079 N/m
ω = (K/M)^1/2 = (117/5)^1/2 = 4.84 / sec
(B) f = ω / 2 pi = 4.84 / 6.28 = .77 /sec
(C) P = 1 / f = 1/.77 = 1.30 sec
Answer:
Normal strain (Ed') = √∆²+L/L - √∆²+L/L
Explanation:
1. it is important to determine Ed' as Ed' = Ed - Ee
Firstly, we determine the lengths between points AB, AC and AD
For AC: /AC/ = √ ∆²c + L²
For AD: /AD/ = √∆²d + L²
For AB: AB = L
2. To calculate the normal strain for point C
Ec' = |AC| - |AB|/|AB|
Ec' = √∆²c + L² - L/L
Now we determine Ed' from the formular Ed' = Ed - Ec
= √∆²d+L/L - √∆²c+L/L
Therefore,
Ed' = √∆²d+L²/L - √∆²c+L²/L
Ed' stands for normal strain
Place the boxes 10cm apart, if they are closer that concentrates the mass of the boxes more
