Homework Statement Draw the schematic diagrams and show the connections for a 10-input AND and OR gate. Homework Equations (a1+a2+...+a10)=(a1+a2+...+a5) +(a6+...+a10) Boolean Equations: AND: multiply each input = output OR: add each input = output The Attempt at a Solution I...

I think I need to take two 5-input AND gates and connect the 10-inputs. Then take 1 2-input AND gate and connect output of two gates to the input of gate. Will the whole system function as a 10 input AND gate? How do I represent that? I've attached my attempt

Homework Statement In the Xilinx software symbol library (student edition version 10.1), the maximum number of inputs for AND and OR gates is 9. What would you do if a 10-input AND and OR gates are needed? Draw the schematic diagrams and show the connections.Homework Equations...

thanks for the clarification!

Homework Statement Sketch the output waveform for the given circuit and inputs (see attachment) Homework Equations For AND gate: x = AB (multiply the inputs to get the output) The Attempt at a Solution attached is my sketch. How to multiply 2 waveforms?

I can't recreate a Matlab example on Matlab 7.12.0 that is straight from the book: How do I call M-function cldesf? This is the error I get: >> [t,x]=ode23('cldesf',[t0,tf],x0t,[],A); ? Error using ==> feval Undefined function or method 'cldesf' for input arguments of type 'double'...

Homework Statement Suppose a non-homogeneous system, Ax = b, of 3 linear equations in 5 unknowns (3x5 matrix) and 3 free variables, prove there is no solution for any vector b. Homework Equations Using the rank theroem: n = rank A + dim Nul(A) where n = # of columns; dim Nul(A) = # free...

IC means the instantaneous center of zero velocity where the general formula is: velocity of a point = angular velocity of the body (cross product) distance of the point relative to the IC for a body having general plane motion (doing translation and rotation). The distance shown in the...

Homework Statement The wheel is rigidly attached to gear A, which is in mesh with gear racks D and E. If D has a velocity of v_D = 5 ft/s to the right and wheel rolls on track C without slipping, determine the speed of gear rack E. Set r = 1.4 ft. Homework Equations angular velocity of...

Rigid, Non-Rigid and System of Rigid Bodies? Homework Statement Classify each of the following items as a rigid body, a system of rigid bodies, or a non-rigid body: a fishing pole, a diving board, a mechanical spring, a bowling ball, a baseball bat, a system of gears, a slider block system...

I found F_r = -3.122 lb and F_\theta = 2.531 lb when a_r = -3.927 rad/s2 and a_\theta = 3.179 rad/s2 What are F_t and N, the magnitudes of the tangential force, F_t, and the normal force, N, acting on the roller when \theta = 102 degrees? a = a_t + a_n a_t = dv/dt (angular velocity) a_n =...

Homework Statement A cam has a shape that is described by the function r = r_0(2 - cos \theta), where r_0 = 2.25 ft. A slotted bar is attached to the origin and rotates in the horizontal plane with a constant angular velocity (\dot{\theta} dot) of 0.85 radians/s. The bar moves a roller...

Homework Statement Which of these bodies has redundant constraints for the given loading conditions? F_1 and F_2 are applied, known forces. In the first choice, the support at A is fixed and a cable connects points B and C. In the second choice, the support at A is a smooth pin, and a cable...

Homework Statement As shown, a roller at point A and a pin at point B support a uniform beam that weighs 42.0 lb. The beam is subjected to the forces F1 = 21.0 lb and F2 = 22.0 lb. The dimensions are L1 = 1.30 ft and L2 = 8.00 ft. What are the magnitudes FA and FB of the reaction forces FA and...

Yes, Thanks so much.
