Problem 2 In the system below, two rigid bodies (Nodes 1 and 3) are connected by four springs to walls on eitherside, as shown in the figure. Nodes 2 and 4 are fixed (wall). An external force of 10 N is applied to body 1 (Node 1). The spring constants are given as kı=10 N/m, k2=20 N/m, k3=30 N/m, and k4=40 N/m. Assume that the bodies can only undergo translation in x-direction (1 DOF). Using the direct method: a) Find the displacements of the two rigid bodies (Nodes 1 and 3). Hint: units! b) Find the reaction force at the left wall (Node 4). Hint: units! E1 F1 E4

A four-bar mechanism is working on horizontal plane. The second link length is 0,4 m and makes an angle of 0=25 degrees with the vertical line as shown in figure. Find the torque (T) in Nm must be applied to link 2 to keep the mechanism in equilibrium against a F=132 N force acting at E on the link 3 downward (along negative y- axis) direction. Allowable tolerance for your answer of this question is relatively 3 percent. So, work precisely and clear while solving it. Do not enter any UNIT. (If the direction of the torque is CCW, just enter the value of it without any sign. If it has CW direction, enter "-" sign "negative sign" before the value such as "- 12,12".)

Two massless springs with different spring constants k₁= 100 N/m and k₂ = 10 N/m are aligned vertically, as shown in figure 1. A block of mass m = 0.12 kg is placed on the bottom spring. The distance between the top of the box and the top spring is h = 0.35 m. You compress the bottom spring Ay = 0.3 m from its equilibrium position (figure 2). When you let go, the box flies up (figure 3) and compresses the top spring (figure 4). Treat the upward direction (↑) as positive, such that the compression of the top spring is a positive displacement. What is the maximum compression of the top spring due to the flying box? Give your answer in units of meters to 2 decimal places. Use g = 9.8 m/s^2. Assume air resistance is negligible. T h EW Ay (2) www Backup link to image (opens in new tab). fumand M риту 4 ² ↑ M ? www
