**Question 2**A sketch of an adjustable-height platform used to load and unload freight trucks is shown below.**How many primary joints are there in this mechanism?**---**Diagram Description:**The image shows a side view of a mechanical loading platform system. It consists of a scissor lift mechanism, which is used to elevate and lower a platform for loading freight trucks.- **Platform:** The top flat surface, inclined upwards on the right side, is used for loading and unloading.- **Mechanism:** The scissor lift mechanism includes several components: - **Two Pairs of Crossed Members:** These are the main arms that form an "X" shape. They pivot in the middle and are connected by bolts, allowing movement. - **Hydraulic Cylinder:** Positioned diagonally across the lower section, this may assist in lifting the platform. - **Fixed Pivot Points:** Located at the bottom ends where the crossed members attach to the base on the left and right sides. - **Load Illustration:** A section on the right shows stacked boxes on a surface level with the platform, indicating where the load is supposed to be placed or removed.The scissor lift mechanism visually includes several primary joints at points where members intersect or connect with the hydraulic cylinder and fixed points.

Primary joints: The primary joints are the joints that have either pure rotational or linear motion.…

A single-piece bicycle crank is shown below under the following load: the rider pedals forward with a vertical force Fp = 500 N on the left pedal and no force on the right pedal. The chain exerts a force Fc on the chainring. The spindle is a solid cylinder with a diameter d = 16 mm. 1. Draw a free-body diagram of the entire crankset and find the reactions at the ball bearings and the force from the chain.
Adjustable Link L m Pivot Pivot Screw 'B' Gripper In the drawing, arm A is being driven back and forth in the direction of the arrows. It is connected to a gripper by way of an adjustable link L, two horizontal bars and two vertical bars. Screw B is a shoulder screw secured to arm A, but allows the horizontal bar to pivot around it. If the shoulder screw B was lowered towards the end of arm A, and the stroke of arm A remained the same, the stroke of the gripper would: Arm 'A' 0 MIMINIA
Examples 2 : A tangential force of 300N affected the tangents on the upper surface of a parallel rectangle of 5cm in height and its upper surface area of 25cm so if you know that the base of the shape is not moving. Calculate (1) shearing stress (2) shearing strain (3) the resulting displacement in the direction of the force knowing that the shear modulus of elasticity of the body material is 4.5 * 101º N / m²?
