To keep a door closed, a wooden stick is wedged between the floor and the doorknob. The stick exerts a 265−N force at B directed along line AB. Replace that force with an equivalent force-couple system at C. The magnitude of an equivalent force at C is ( N)i+( N)j+( N)k. The magnitude of an equivalent couple at C is MC = ( N⋅m)i+( N⋅m)j+( N⋅m)k.

A CMOS circuit is shown in Fig. P9.5. Suppose that the precharge transistor was chosen such that node X is guaranteed to be charged to VDD. All nMOS transistors have W/L = 20. Determine how long it takes for the node voltage at X to decrease to 0.8VDD after the clock signal pulse goes to high (with zero rise time) when input voltages at A, B, D are 1.2 V and the input voltage at C is zero. Assume the following parameter values: γ = 0.0 V1/2 • VT0 = 0.48 V • k 0 n = 102µA/V2 a Ec,nLn = 0.4 Hint: The nMOS transistor tree between node X and the ground can be approximated by an equivalent transistor with an effective W/L. Hint 2: You need to solve a super easy integral.

Elementary row operations on an augmented matrix never change the solution set of the associated linear system. Determine whether the statement below is true or false. Justify the answer. Choose the correct answer below. A. The statement is false. Interchanging two rows never changes the solution set of the associated linear system. However, scaling a row by a nonzero constant can change the solution set of that system. B. The statement is true. Each elementary row operation replaces a system with an equivalent system. C. The statement is true. Elementary row operations are always applied to an augmented matrix after the solution has been found. D. The statement is false. Interchanging two rows never changes the solution set of the associated linear system. However, replacing one row by the sum of itself and a multiple of another row can change the solution set of that system.

The floor of an airplane cargo bay is shown in a horizontal position. Take the value of P to be 1150 N. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Problem 04.089.b - Resultant Force and Moment of a System of Forces Determine an equivalent force system consisting of a single force, and specify the x and z coordinates of the point where the force's line of action intersects the floor. (Include a minus sign if required. ) The resultant force in the x direction of the equivalent force system consisting of a single force is N. The resultant force in the y direction of the equivalent force system consisting of a single force is N. The resultant force in the z direction of the equivalent force system consisting of a single force is N. The x coordinate of the point where the force's line of action intersects the floor is m. The z coordinate of the point where the force's line of action intersects the floor is m. (Round the final answer to four decimal places.)
