A freeway sign measuring 12 ft by 6 ft is supported by the single mast as shown. The sign, supporting framework, and mast together weigh 600 lb, with center of gravity 10 ft away from the vertical centerline of the mast. When the sign is subjected to the direct blast of a 75-mi/hr wind, an average pressure difference of

- A 4-m-diameter water tank consists of two half cylinders,each weighing 4.5 kN/m, bolted together as shown inFig. . If the support of the end caps is neglected,determine the force induced in each bolt.arrow_forwardThe volume and the average density of an irregularly shaped body are to be determined by using a spring scale. The body weighs 7000 N in air and 4700 N in water. Determine the volume and the density of the body. State your assumptions.arrow_forwardAn Olympic lifter (m = 103kg) is holding a lift with a mass of 350 kg. The bar exerts a purely vertical force that is equally distributed between both hands. Each arm has a mass of 9 kg, are 0.8m long and form a 40° angle with the horizontal. The CoM for each arm is 0.5 m from hand. Assuming the lifter is facing us in the diagram below, his right deltoid inserts 14cm from the shoulder at an angle of 13° counter-clockwise from the humerus. Find the force right deltoidarrow_forward
- **28. A man drags a 72-kg crate across the floor at a constant velocity by pull- ing on a strap attached to the bottom of the crate. The crate is tilted 25° above 0.90 m the horizontal, and the strap is inclined 61% 61° above the horizontal. The center of gravity of the crate coincides with its 0.40 m geometrical center, as indicated in the drawing. Find the magnitude of the tension in the strap. 25°arrow_forwardA closed cylindrical container of length 0.6 m and diameter 0.3 m is full of oil of sg = 0.85. It is rotated on its vertical axis at 250 RPM. Determine the force exerted on the bottom plate (N).arrow_forwardes Channel AB is fixed in space, and its centerline lies in the xy plane. The plane containing edges AC and AD of the channel is parallel to the xz plane. The surfaces of the channel are frictionless and the sphere E has 1.8 kg mass. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. 4.552 N D 30° T 4.552 N A 30° E X 20° B 30° Determine the force supported by cord EF, and the reactions RC and Rp between the sphere and sides C and D, respectively, of the channel. (Round the final answers to four decimal places.) The force supported by cord EF is 11.5253 N. The reactions RC and RD between the sphere and sides Cand D, respectively, of the channel are as follows: RC= RD=arrow_forward
- A rigid gate of a flood control structure in a river is 6 m wide by 4 m high and weighs 10 kN. With its longer edge horizontal, it is moved up and down with its short edges sliding in vertical channel guides. Evaluate the force, in kN, needed to raise the gate when the surface of the water is 2 m. above its top edge. There is no water on thedownstream side of the gate. The coefficient of friction between the gate and the channel guides is 0.10. Neglect the buoyant effect of the water on the gate and the weight of the cables connected to the gate.a. 104 b. 94 c. 110 d. 92arrow_forwardIn order to burgle a local McDonald's, the Hamburglar must climb onto the roof. To do this, a ladder of length 3.31 m and mass 21.2 kg is placed leaning against a vertical wall, as shown in the image below. There is negligible friction between the ladder and the wall, but the same is not true for the ladder and the ground: us ≠ 0 between those two surfaces. Even with that friction, the ladder will start slipping if the angle ø ladder makes relative to the ground is less than 71.0°. Assuming the ladder is uniform (so that its center of gravity is located at its geometric center), what must be the maximum static frictional force (in N) that exists between the bottom of the ladder and the ground? Explain how you solved the problem involving a ladder leaning against a wall. Be sure to state what your known and unknown quantities are, what concepts were applied, and what equations were used!arrow_forward4. An airplane weighing 5500 kg is in a steady level flight with a speed of 225 m/s. The pilot initiates a steady pull-up maneuver with a radius of curvature of 775 m. The location of center of gravity (CG), center of pressure on wing (CP) and point of action (T) of tail force are marked in the figure. Use g = 9.81 m/s³. Neglect drag on the tail and assume that tail force is vertical. Assuming the engine thrust and drag to be equal, opposite and collinear, the tail force kN (round off to one decimal place). 20 cm CGarrow_forward
