3. Determine the unstretched length of DB to hold the 40kg crate in the position shown. Take Spring constant, k - 180N/m? wwww (1)

Need help, include all steps and units please and thanks.

k1 = 80 N/mm, k2 = 100 N/mm, k3 = 160 N/mm, F3 = 200 N, F4 = 100 N find displacement in node 3 and 4. Calculate the reaction forces in node 1 and 2. k₁ 12 F3 k₂ 3 k₂ nim FA 4

Refer to Fig. P6–9. Given that the tension T in cable AC is 900 N, determine exerted on point C. 6-9 AC the components of TAC 3.5 m 2 m B. 2 m 4.5 m FIGURE P6-9

Answer part a, b and c

I need it very fast and correct very fast and only handwritten Or skip I'll dislike if not follow these rules please I'll like do handwritten both parts fast

Determine the normal tension of the cylinder piston rod (diameter 32mm). The clamping force of the pliers is 6000N. The dimensions of the structure are: x1 = 10 mm x2 = 120 mm y1 = 110 mmy2 = 798 mm   Use the units [N, mm], ie the answer comes in MPa !!! Please enter a numeric value only !!

Determine the required length of cord AC in Fig. 3-8a so that the 8-kg lamp can be suspended in the position shown. The undeformed length of spring AB is l'AB= 0.4 m, and the spring has a stiffness of KAB 300 N/m. - إحسب الطول المطلوب للحبل (AC) اللازم لتعليق مصباح كتلته (kg 8) كما في الشكل ، علما ان الطول الاصلي m 824.0 C (KAB = 300 N/m) di Jales (0.4 m) (AB) i 2 m KAB = 300 N/m 30° B

what is the compression in 2 springs after the block A with 50 N is falling off on it from the rest note :-Initially both springs are unstretched. A 10m 5m 20N/m = 30 N/m
