PROBLEM 3: For the given system below, determine the reaction at points A and B. Also, determine the required coefficient of friction at point B. The body's weight is given as 490 N. 0.4m

The crate pulled by a man as shown weighs 200 N. Supposed that the static friction coefficient between the contact surfaces is 0.25. Determine the following: a.) The value of angle alpha (ᾳ) to obtain the smallest possible value of the pulling force the man exerted so that the crate is on the verge of moving. b.) The smallest value of the pulling force the man exerted, c.) The normal reaction between the contact surfaces (Crate and Horizontal floor).

Q4: The uniform box shown in next figure, has a mass of 40 Kg. If the two forces T = 60 N and F =30 N are applied on the box, determine if it remains in equilibrium. The coefficient of static friction (H) = 0.24 F=30N T=60N 30 40 Kg

The crate shown has a mass of m 20 kg and is being pulled up a plane at 0 25 degrees (to the horizontal) by a cord parallel to the plane, as shown in the following figure:     You are given that the coefficient of friction is u = 0.3.   State the following:   The component of weight parallel to the surface: N.   The component of weight perpendicular to the surface: N.   The normal reaction: N.   The frictional force: N. Calculate the magnitude of the tension, P, in the chord necessary to give an acceleration parallel to the plane of 4 m/s². P is equal to N.

The frame supports the 400 kg mass as shown. Assume a coefficient of friction of 0.25 around the pulley. Further assume the frictional forces are fully developed. Determine all external reactions and all pin reactions acting on the structure. pleas show me all your work

Given the figure shown below, what is the mass of block B on the smooth incline if the system is in static equilibrium? A rope runs from block B up around the frictionless pulley at A down to a 10 kg counterweight. A 1 m B- 1m 10 kg 45°

Problem 3 - Determine whether the block shown is in equilibrium. Find the magnitude and direction of the friction force. Ms=0.30 MK=0.20 400 N 300N 130 45°
