It is supported at one end by a pin and at the other end by a post having a mass of 50 kg and negligible thickness. Determine the minimum force \( P \) needed to move the post. The coefficients of static friction at \( B \) and \( C \) are \( \mu_B = 0.4 \) and \( \mu_C = 0.2 \), respectively.**Diagram Explanation:**- The diagram illustrates a beam \( AB \) with a triangular distributed load gradually increasing to 800 N/m at point \( B \).- Point \( A \) is a fixed pin support, allowing rotation but preventing translation.- At point \( B \), the beam extends 2 meters horizontally from point \( A \).- A vertical column at point \( B \) is 400 mm (0.4 meters) high, resting on a post \( C \), which is 300 mm (0.3 meters) tall.- The post \( C \) is connected to a force \( P \) applied at the top of the post, with an inclination described by a \( 3-4-5 \) triangle.- The coefficients of static friction are specified for points \( B \) and \( C \).This setup implies a calculation for the minimum force \( P \) to overcome static friction and move the post supporting the beam under the given loading.

8-45. The beam AB has a negligible mass and thickness and is subjected to a triangular distributed loading. It is supported at one end by a pin and at the other end by a post having a mass of 50 kg and negligible thickness. Determine the minimum force P needed to move the post. The coefficients of static friction at B and C are µg = 0.4 and #c= 0.2, respectively.
