Consider four springs with spring constants k1= 20N/m, K2=50 N/m, K3=100 N/m, K4=200 N/m, What is the equivalent spring constant if K234 are in parallel and with K1 in series. O 128.95 N/m O 285.35 N/m 370 N/m O 18.92 N/m

Suppose you have three springs with force constants of K₁ = K₂ = K3 = 3.30 × 10³ N/m. What is their effective force constant if one is hung from the other in series? You may assume the springs have negligible mass. N/m

A camera tripod is set up as shown below. The tripod is pretty fancy and has self-balancing legs. The camera weighs 47 N. Felicia Filmmaker has positioned the tripod as follows: CA=-4 myA=0 m zĄ = 6 m B = -2 myB = 0 m zB = -6 m xc = 6 myc = 0 m zc = -4 m xD = 0 myD = 12 m ZD = 0 m Python input: X_A = -4 y_A = 0 Z_A = 6 X_B = -2 y_B = 0 Z_B = -6 X_C = 6 y_C = 0 Z_C = -4 X_D = 0 y_D = 12 Z_D = 0 Action! A Z number (rtol=0.01, atol=1e-05) number (rtol=0.01, atol=1e-05) number (rtol=0.01, atol=1e-05) y D B --- X Determine the magnitude of the force in each leg of the tripod to keep it in equilibrium: FAD = FBD = FCD = N ?

Q2/ In the nucleus pulposus of an intervertebral disc, the compressive load is 1.5 times the externally applied load. In the annulus fibrosus, the compressive force is 0.5 times the external load. What are the compressive loads on the nucleus pulposus and annulus fibrosus of the L5-S1 intervertebral disc of a 90 kg man holding a 50 kg weight bar across his shoulders, given that 63% of body weight is distributed below the disc?
