1.
The figure shows a car jack to support 400kg (W=400kg). In the drawing, the angle (0) varies
between 15 and 70 °. The links are machined from AISI 1020 hot-rolled steel bars with a
minimum yield strength of 380MPa. Each link consists of two bars, one on each side of the
central bearings. The bars are 300mm in length (/) and 25 mm in width (w). The pinned ends
have the buckling constant (C) of 1.4 for out of plane buckling. The design factor (nd) is 2.5.
(1) Find the thickness (t) of the bars and the factor of safety (n).
(2) Check if the bar is an Euler beam.

If the coefficient of static friction between his shoes and the ground is \( \mu_s = 0.4 \) and between the crate and the ground is \( \mu_c = 0.3 \), determine if the man is able to move the crate using the rope-and-pulley system shown. **Diagram Explanation:** The diagram illustrates a scenario where a man is attempting to pull a crate using a rope-and-pulley system. The setup is as follows: - **Crate (C):** Positioned on the ground with a rope attached. - **Rope:** Connects the crate to a pulley system and extends to the man. - **Pulley on Tree:** The rope runs over a pulley mounted on a tree which redirects the rope. - **Angles:** - The rope between the crate and tree forms a \(30^\circ\) angle with the horizontal. - The rope between the tree and the man makes a \(45^\circ\) angle with the horizontal. - **Man (A):** Pulling on the rope with the intention of moving the crate.
